Two days on, most of the count is in and the remaining races are the ones that resist easy reading. The panel, now seven, takes them one at a time: what the procedures allow anyone to infer, what the polls said beforehand, and which of its own claims from Tuesday night did not hold up.
- AP reports that Democrats will control both chambers next year. NBC’s House model estimate: 259 Democratic seats (the same page also says at least 258). AP counts 35 uncalled House races in which party control of the seat is at stake.
- Alaska Senate (not called): Peltola 102,962, Sullivan 102,325 first choices, a 637-vote gap with about 74% counted (AP); nobody near 50%, so ranked rounds are targeted for Nov. 18. Ballot Measure 2, repealing the system, trails 48.15% Yes to 51.85% No (Division of Elections, Nov. 4).
- Mississippi Senate (not called): Colom leads Hyde-Smith by 1,145 votes with 96% counted (AP, 1:11 PM ET); ABC’s table at 11:30 PM ET shows 1,813. Provisional ballots are due to be resolved by Nov. 10. Plurality rule, no runoff (CBS).
- Also uncalled by AP: governor in Alaska and in Kansas.

Special session: Alaska and ranked-choice voting
Where the count stands
Ida: The Division of Elections’ unofficial summary (stamped 1:09 PM, Nov. 4; the latest official count we found Thursday night) has Mary Peltola at 102,962 first choices (48.02%) and Dan Sullivan at 102,325 (47.72%), a 637-vote gap; Gerald Heikes 4,846, Daniel J. Sullivan Jr. 3,600, write-ins 695. AP, which has not called it, estimates the count at about 74%. Domestic mail postmarked by Election Day counts if it arrives by Nov. 13 (Nov. 18 from overseas); ranked rounds are targeted for Nov. 18. The House (Nick Begich, 49.52%) and governor (Kreiss-Tomkins, 48.99%) may go to rounds too.
Bayes: Tuesday night (3:19 AM ET) Sullivan led 48.7 to 47.5 on NBC’s count at 66.1%, and I said the rest had to run about 2.3 points toward Peltola to flip it. It flipped. No batch margin from that: the 66.1% was against NBC’s expected vote, the 74% is AP’s estimate, and differencing two denominators measures the denominators.
Hez: Ballot Measure 2, repealing the top-four primary and ranked general elections, trails 98,460 Yes (48.15%) to 106,040 No (51.85%), 399 of 400 precincts in. If that holds, the Senate race will be tabulated by a procedure its electorate declined, at the same sitting, to repeal: a procedure ratifying itself. The menu and the rule for reading it shared a sheet of paper, so a voter could choose the rule purely instrumentally, by its expected effect on the candidates it would rank.
Ida: Condition: we found no official statement of when a repeal would take effect, so we do not claim a Yes would reach Nov. 18.
Rick: The measure was the ballot’s one easy question. With two options, May’s theorem leaves simple majority as the only anonymous, neutral, positively responsive rule. Trouble starts at three.
2022, the canonical case
Rick: As in the August 2022 House special. Round one: Peltola 75,799 (40.19%), Palin 58,973 (31.27%), Begich 53,810 (28.53%). Begich’s ballots went 27,053 to Palin, 15,467 to Peltola, 11,243 exhausted; Peltola won the final 91,266 to 86,026. The published pairwise counts (Graham-Squire and McCune; Clelland) have Begich beating Peltola 87,859 to 79,451 and Palin 101,217 to 63,618. The Condorcet winner went out first. I have been waiting all week to say so.
Rick: Graham-Squire and McCune also build two paradoxes from those ballots. Move 6,000 Palin-only ballots to Peltola-first and Palin drops below Begich, who then beats Peltola: she loses by gaining support. Remove 6,000 Palin–Begich–Peltola voters and the same happens: they do better staying home. Against the official round one, Palin falls to 52,973, under Begich’s 53,810; on the published pairwise counts, Begich then wins by 2,408.
Medi: Center squeeze. First choices piled up at the wings, and the candidate every pairwise majority preferred had the thinnest first-choice base. IRV orders eliminations by top preferences among the candidates still standing, which Black’s theorem never consults.
Ida: And the majority was of continuing ballots: with 14,997 inactive by the final round, Peltola’s 91,266 was 51.48% of those continuing and 47.46% of the 192,289 cast.
What the first choices can and cannot tell us
Ida: In 2026 the finalists are fixed by arithmetic: Heikes, Sullivan Jr. and the write-ins hold 9,141 first choices, under a tenth of either leader. With finalists A and B, A wins iff \( a_1 + t_A \gt b_1 + t_B \), where \( t \) counts ballots transferred from eliminated candidates; the rest exhaust. Let \( x, y \) be the shares of the 9,141 reaching Peltola and Sullivan. On current first choices Peltola leads the final round iff \( 637 + 9141\,(x – y) \gt 0 \), i.e. \( y – x \lt 637/9141 \approx 0.070 \). If none exhaust, Sullivan finishes ahead iff he takes more than 53.48% of them; if a fifth exhaust, more than 54.36% of the rest. Conditional on a growing count; not a forecast. Round one will not match the summary exactly, since individual write-ins are excluded and those ballots’ next rankings count.
Medi: Which makes this race friendlier to the median voter theorem than 2022 was: with the finalists fixed, the last round is a pairwise vote.
Rick: Among ballots that rank either. Nor do first-choice counts rule out Heikes, at 2.26%, being the Condorcet winner. Begich, at 28.53%, was one. Only rankings settle it.
The cast-vote record and the junk drawer
Bayes: The Division posted a cast-vote record on Nov. 4: 204,530 ballot records against 215,906 Senate ballots on the summary. In that file the first-choice leader reverses: Sullivan 99,470, Peltola 95,631.
Ida: Because the file is a selected subset. The Division says it holds scanned ballots, not those counted only by hand; we have not confirmed hand counts explain the whole 11,376-ballot gap (5.3%). That gap is the junk drawer, and the scanner is the instrument deciding what we see. If file and summary describe the same moment, the drawer must hold 7,331 Peltola and 2,855 Sullivan first choices, 964 for the others, and 226 with none valid: a 4,476-vote Peltola lead that offsets the file’s 3,839-vote Sullivan lead to give the official 637.
Bayes: Granted for first choices. But transfers are rankings conditional on first choice. If a hand-counted Heikes voter ranks like a scanned one, the file identifies the transfer rates your inequality needs.
Ida: That “if” is the identification assumption. The drawer runs Peltola +40.1 points among valid first choices; the file runs Sullivan +1.9. A 42-point difference on first choices and none on second choices needs an argument, and the file cannot supply it, since the file is exactly what lacks the other group.
Bayes: Untestable from the file. Testable on Nov. 18.
Ida: When nobody needs it. Anyone can run the Division’s rules on the file tonight; out comes the instant-runoff winner of the scanned ballots, an electorate that does not exist. We are not reporting it.
Two Sullivans on one ballot
Ida: The Division lists Daniel J. Sullivan Jr. (AP: Dan J. Sullivan) alongside Sen. Dan Sullivan; the matter is in litigation, and we take no view on it. The procedural point: in the final round a ballot counts for whichever finalist it ranks higher, so a voter who ranked Sullivan Jr. first and the senator second loses nothing when Sullivan Jr. is eliminated. Under plurality the same confusion is a pure loss.
Rick: The ranked ballot converts confusion into exhaustion, costing only ballots that rank Sullivan Jr. and neither finalist, or skip two consecutive ranks or overvote before reaching one. The round-by-round report counts them.
Polly: Response error with no validation sample. A deliberate vote for Sullivan Jr. and a mistaken one are the same ballot, so the 3,600 is observationally equivalent across every mix of intent.
What the polls could say
Polly: Standing caveat: errors against a count near 74% partly describe which ballots are still out. The final averages as listed in Wikipedia’s aggregate table (a pointer; not checked at the aggregators) had Peltola ahead 49.2–48.2 (RCP), 49.2–47.8 (DDHQ) and 48.3–45.9 (Silver Bulletin): misses of 0.7, 1.1 and 2.1 toward Sullivan against the official 0.30-point first-choice margin. The larger problem is the estimand. RCP’s two numbers sum to 97.4, and nothing says whether the other 2.6 is undecided, Heikes, the other Sullivan, or someone who would rank all four. The count puts 4.26% outside the top two, the very ballots Ida’s inequality runs on. The polls measured first choices; the rules count final rounds.
The governor’s race: ranking as coalition
Hez: AP reports state Republican leaders urged voters to rank all three Republicans. Kreiss-Tomkins has 103,837 first choices (48.99%); Wilson 61,734, Bronson 30,003, Taylor 15,763, together 107,500 (50.72%). Under plurality, split three ways, its strongest member sits 19.86 points behind. Coordinated ranking asks the tabulation to reassemble it.
Ida: Conditionally, on current first choices: Taylor goes first, then Bronson (Bronson plus all of Taylor is 45,766, below Wilson’s 61,734). The pool, with write-ins, is 46,377 against a Kreiss-Tomkins lead of 42,103. Wilson finishes ahead iff his transfers beat Kreiss-Tomkins’s by more than 90.8 points of the pool: the exhausted share plus twice the crossover share must stay under 9.2%.
Hez: So a coalition of 50.72% on paper exists on the ranked ballot only as far as its voters rank to the end. The instruction’s force is measured by the exhaustion rate.
Conservation of impossibility
Hez: Back to Ballot Measure 2. Repeal would restore party primaries. That does not delete the three-Republican problem; it hands it to a primary electorate before November.
Ida: Conservation of impossibility. With three or more candidates, Arrow says no ranking rule meets all of his conditions and Gibbard–Satterthwaite says every non-dictatorial rule that can elect any of them rewards strategic misreporting at some profile; retention keeps those costs in the tabulation and the exhausted ballot, and repeal moves them into the primary and the spoiler.
Rick: Then the measure decides where Alaska keeps its paradoxes, not whether.
Ida: And it asks that as a yes-or-no question, the one format in which the rule is not in dispute.

CVR-derived figures and all thresholds are the panel’s arithmetic.
Mississippi: a near-tie, a third candidate, and a plurality rule
Ida: First, the question we left open. On Tuesday night the panel declined to say whether Mississippi’s Senate race could go to a runoff, because we could not verify the rule; the state does require majorities for its statewide state offices, under a 2020 amendment to Section 140 of its constitution. As reported, the regular Senate general election is decided by plurality, with no runoff. CBS News reported Thursday that the plurality leader wins. That is news reporting; none of us has read the statute.
Rick: That changes what my Tuesday entry was about (Tuesday night, 1:25 AM ET). I wrote that the head-to-head order of the two leading candidates turned on how Pinkins’s voters ranked them, which the ballots do not record. With margin \(M\), Pinkins vote \(P\), and \(f\) the share of Pinkins voters preferring the trailing candidate, the pairwise order reverses iff \(f > \frac{1}{2} + \frac{M}{2P}\). Put in AP’s Thursday margin, \(M = 1{,}145\), and my Tuesday lower bound \(P \geq 19{,}380\) (a rounded 2.1 percent, so at least 2.05 percent, of 945,464 counted; NBC, Tuesday night, 1:23 AM ET), and the threshold is at most \(0.5 + 1{,}145/38{,}760 \approx 0.53\). Under plurality, \(f\) appears nowhere in the rule, so the inequality is now about a counterfactual majority, not the outcome: the roughly 2 percent who voted Pinkins carry no second preferences at all, because no tabulation asks for them.
Ida: The count has its own residual. The margin moved from 28 votes (NBC News live blog, Tuesday night, 2:40 AM ET) to 1,145 with 96 percent counted (AP, 1:11 PM ET Thursday). Other outlets’ tables have shown different margins at different hours; we anchor on AP’s, since AP is the one calling the race. ABC News’s table at 11:30 PM ET Thursday showed a larger gap, 466,775 to 464,962, or 1,813 votes. AP reports several thousand provisional ballots still to be resolved, by November 10, and notes that about 5,700 were counted in 2022. Let \(N\) be the provisionals that count and are cast for one of the two leading candidates, and \(s\) the trailing candidate’s share of them. The trailing candidate nets \((2s-1)N\), so closing the gap requires \(s > \frac{1}{2} + \frac{1{,}145}{2N}\). At \(N = 3{,}000\): \(1{,}145/6{,}000 \approx 0.191\), so \(s > 0.691\). At \(N = 5{,}700\): \(1{,}145/11{,}400 \approx 0.100\), so \(s > 0.600\). At ABC’s 1,813 the same two cases require \(s > 0.802\) and \(s > 0.659\). At \(N \leq 1{,}145\) the threshold reaches 1 and no share suffices, which is AP’s calling criterion (call only when no scenario closes the gap) restated in this notation. These are conditional statements about what the arithmetic requires, not forecasts. Mail ballots received by November 10 (ABC News) enter the same expression with their own \(N\) and \(s\).
Bayes: And \(s\) is the one parameter the counted vote cannot supply. Provisional ballots come from voters whose eligibility was questioned at the polls, which is not a random draw from the electorate. The 2022 figure gives the scale of \(N\); it says nothing about the sign of \(2s-1\).
Ida: That is the junk drawer. The procedure files the ballots it cannot decide on the spot into a residual category, and when the margin is roughly a tenth of a percent of the vote, the residual category is where the decisive ballots sit.
Hez: Then the remedy. The Secretary of State’s office confirmed to ABC News that Mississippi has no formal recount process, automatic or requested. After certification, due November 13 (ABC News), a candidate may examine the ballot boxes and go to court; AP adds that a challenger can seek a court-ordered recount. That changes what a concession means. In Nebraska a margin within 1 percent of the leader’s total triggers a recount automatically; Mississippi’s margin, at most a quarter of one percent of the leader’s total, would sit well inside it. Where the recount is automatic, every trailing candidate waits, strong case or weak, so waiting conveys nothing: a pooling equilibrium. Here, once certification closes the count, the only way to keep the option is to sue, at a cost \(c\) that is financial and public. The trailing candidate continues iff \(p(M)\,B > c\), with \(p(M)\) the probability that a contest overturns margin \(M\) and \(B\) the value of the seat. The choice separates: a suit reveals that the campaign’s estimate of \(p\) clears the bar, a concession that it does not. Until certification the option costs nothing, since counting continues regardless; the informative decision comes after.
Rick: And whatever the remedy, it re-measures the plurality. Neither a box examination nor a court-ordered recount asks the Pinkins voters anything.
Hez: For a Senate seat, the courts are not the last forum: Article I, Section 5 makes each chamber the judge of the elections of its own members.

With no senator outside the two columns, the threshold is \(d \ge 51 + k\)
Agnes: On Tuesday night Nebraska was the seat the two-column count could not file: Osborn (I) 46.2, Ricketts (R) 48.0 with 58.6% in (Tuesday night, 12:25 AM ET, NBC). NBC News now projects Ricketts, 50.4 to 43.6 with 94.1% expected in (NBC Senate page, updated 11:18 PM ET Thursday; the page does not show when the projection was made). AP’s Thursday list of Senate and governor races it has not called (AP, updated 1:11 PM EST, Nov. 5) does not include Nebraska. If the projection stands, every senator sits in one of two columns, and the organizing condition I wrote at 11:48 simplifies. Democrats organize, with the Vice President breaking ties, iff \(d – k > r + k\), where \(k\) is the number of Democrats who vote with the other column. Set \(r = 100 – d\): then \(2d – 100 > 2k\), so \(d \ge 51 + k\), and the tolerated number of defections is \(k = d – 51\).
Agnes: NBC’s called count is D 54, R 44, with Alaska and Mississippi uncalled (same page, 11:18 PM ET). I have not checked the 54 against a second source. Both uncalled seats go to one column or the other, so there are four outcomes:
- AK and MS both R: \(d = 54\), \(r = 46\), \(k \le 54 – 51 = 3\). Check: \(51 > 49\) at \(k = 3\); at \(k = 4\), \(50 = 50\) and the tie goes to the Vice President.
- AK D, MS R: \(d = 55\), \(k \le 4\). Check: \(51 > 49\).
- AK R, MS D: \(d = 55\), \(k \le 4\), as above.
- AK and MS both D: \(d = 56\), \(k \le 5\). Check: \(51 > 49\).
Agnes: John’s 11:41 note set the threshold: 51 is the answer only at \(k = 0\), and 52 is the answer at \(k = 1\), the one defection his note builds in. Each seat past 51 buys one more defection: the indeterminacy has moved from the seat count to \(k\), which no results page reports.
Hez: Tuesday night NBC’s table for this race showed no Democratic line, and I headlined that as an empty line. The sources did not support the headline: they conflict on whether a Democratic nominee stayed on the ballot, and nothing I have found since settles it. So whether the absence of a line did anything is unidentified. Osborn’s 43.6 reads as consolidation of a pairwise contest, or as the ceiling of an independent campaign; NBC’s table folds any transfer into his total, so the two are observationally equivalent.
Agnes: A projection is not a certification: the statute sets the State Board of Canvassers’ meeting for the fourth Monday after the election, Nov. 30 this year (as summarized; we have not read the full text). The arithmetic holds while the seat is filled as NBC projects.

The House tail: NBC’s estimate needs 10 Democratic seats from the last 29; on Tuesday night it needed 24 from 60
Ida: NBC’s House page has 249 seats called for Democrats, 157 for Republicans, 29 uncalled (updated 11:18 PM ET Thursday). AP counts 35 uncalled House races in which party control of the seat is at stake (updated 1:11 PM EST). These are not two measurements of one set. AP’s set is a restriction: a contest whose finalists share a party puts no party control at stake, so AP’s count of all its uncalled races is at least 35. The restriction cannot explain why AP’s number is larger. Two things can: the counts are ten hours apart, and they come from two desks with their own calling rules. The sources do not divide the gap of six between time and desk, and neither will I.
Medi: My own inference. On Tuesday night (3:19 AM ET) NBC had 231 Democratic seats called, 144 Republican, 60 uncalled, and an estimate of 255 Democratic seats. The estimate implied the 60 would go \(255 – 231 = 24\) Democratic, or \(24/60 = 40\%\), against \(231/375 = 61.6\%\) in the called set. Since then, net, 18 Democratic and 13 Republican seats have been called: 31 calls at \(18/31 = 58.1\%\). NBC’s estimate now reads 259, an 83-seat majority (\(259 – 176\)); the same page also says at least 258. For 259 to hold, the 29 must split 10 to 19: \(10/29 = 34.5\%\) Democratic (at 258, \(9/29 = 31.0\%\)). The called set stands at \(249/406 = 61.3\%\).
Medi: So the first half of my pool to be called ran 58%, not 40%. Either the 40% was wrong, or the calling order took that pool’s Democratic-leaning seats first; from called counts alone the two are observationally equivalent. The model’s revision separates them in part. Had the 40% been right and order alone at work, the last 29 would need only \(24 – 18 = 6\) Democratic seats, 20.7%. NBC’s estimate rose four seats instead. Does the residual still differ from the called set? More than before: the gap between the called share and the implied uncalled share was 19.1 points on Tuesday night at 2:05 AM ET (61.5 against 42.4), 21.6 at 3:19 AM ET, and is 26.8 now.
Agnes: One thread closes regardless. On Tuesday night (3:05 AM ET) I said the override pivot would pass from the Senate to the House only if the House majority finished below about 246 seats. With 249 called, that branch is gone.
Bayes: Per NBC, 20 of the 29 sit in six states: California 6, Florida 4, Arizona 3, North Carolina 3, Colorado 2, Washington 2. Their late ballots differ from early ones for reasons written into the rules. California counts mail postmarked by Election Day that arrives within seven days, and counties certify by Dec. 3 (the date from the Secretary of State, the window from secondary summaries). Washington ties its receipt deadline to the day before certification (secondary). Arizona, Florida, North Carolina and Colorado require mail to arrive by Election Day, with later windows for military and overseas ballots in the last three (secondary and county sources). There a ballot counted Thursday was cast by Tuesday; Arizona verifies signatures on Election Day drop-offs after polls close (a county statement, via secondary sources). Late in the count need not mean late in the electorate; in the postmark states it can mean both. Either way the count is sorted on arrival and processing time, which correlate with how people vote. That makes late batches systematically different from early ones; it does not give the sign.
Ida: The sign sits in the junk drawer. Let \(M\) be a seat’s final margin in votes and \(M_c\) its counted margin. Then
\[ M = M_c + \sum_j n_j m_j , \]
where \(j\) runs over residual categories (late-arriving mail, cured ballots, provisionals), \(n_j\) is the number in category \(j\) that end up counted, and \(m_j \in [-1, 1]\) is the margin within it. Voters choose \(m_j\); the rules choose \(n_j\). A ballot enters the cure category only if the signature check flags it, and leaves it only if notice reaches the voter before the deadline: noon on the third business day in North Carolina; five days in Arizona, calendar or business depending on the source (secondary). I found provisional-adjudication rules for none of the six states. What we observe is \(M_c\), plus bounds \(\bar{n}_j\) the rules imply. AP says it calls a race only when no scenario lets the trailing candidate close the gap; one formal reading is \(|M_c| > \sum_j \bar{n}_j\), the counted margin exceeding everything the drawer could hold at \(m_j = \pm 1\). A seat stays uncalled until that is shown. The rest is Bayes’s model of \(m_j\).
Ida: Maine’s Second adds a compartment. NBC on Thursday: LePage 49.9, Dunlap 48.3, 97.8% in. On Tuesday night (3:19 AM ET) NBC showed Dunlap 50.1, LePage 49.9 at 82.6%. Tuesday’s shares sum to 100.0, Thursday’s to 98.2. Until it is clear whether a line was added or a figure is stale, the batch between them is not identified; I report both. Maine’s ranked tabulation runs only if three or more candidates are on the ballot and no one has a majority (secondary summaries of Maine’s rules). The leader is below 50; no source I have settles the first condition.

7. Were the polls right?
The standing caveat first. Every error below is measured against a count that is not final, so part of each number is a statement about which ballots are still out. Late-counted ballots moved margins all Tuesday night. Mississippi stood at Hyde-Smith 49.9, Colom 48.0 with 90.9 percent counted (Tuesday night, 11:54 PM ET), at 48.9 apiece with 95.6 percent (Tuesday night, 3:17 AM ET), and at Colom 49.0, Hyde-Smith 48.9 with 95.7 percent (NBC, 11:18 PM ET Thursday): two points of margin on under five percent of the vote. Two Senate races remain uncalled by the AP: Alaska (about 74 percent counted, ranked-choice tabulation possible) and Mississippi (about 96 percent, provisional ballots outstanding). Both appear in the table; neither enters the headline means. Maine, at about 93 percent, stays in; Nebraska, with an independent in second place, is treated separately below.

Margins in points, Democrat minus Republican. Error = result margin minus final average; positive means the Democratic candidate ran ahead of the average. DDHQ rows updated Nov 2–3. *Nebraska error is Osborn minus Ricketts, a convention discussed below. Alaska and Mississippi are shown but excluded from all means. Montana is omitted: a three-way Republican/independent/Democratic race, and NBC’s page as read lacked the independent’s share.
On the eleven called two-party races, the errors against RCP are 9.5, 8.6, 7.0, 2.0, 4.1, 0.9, 2.8, 1.7, 9.4, 5.7 and 4.9. They sum to 56.6, so the mean signed error is \(56.6/11 = +5.15\) points. None is negative, so the mean absolute error is also 5.15. Against DDHQ the same eleven sum to 50.6: mean signed error and MAE both \(50.6/11 = +4.60\). The aggregators differ by at most 2.7 points on any race (South Carolina) and agree on every sign, which is weak corroboration, since they average largely the same polls.
The useful decomposition is \(e_s = \mu + \varepsilon_s\): a component \(\mu\) common to every state plus a state-specific residual \(\varepsilon_s\) with mean zero. Eleven errors of one sign are evidence about \(\mu\), not eleven findings about eleven sets of pollsters: they are mostly one draw of \(\mu\), observed eleven times. Against RCP, \(\hat\mu = \bar e = 5.15\). The residuals \(e_s – \hat\mu\) run from \(0.9 – 5.15 = -4.25\) (Kansas) to \(9.5 – 5.15 = +4.35\) (Texas); their squares sum to 99.2, so their standard deviation is \(\sqrt{99.2/10} \approx 3.15\), and the standard error of \(\hat\mu\), if the residuals were independent, about \(3.15/\sqrt{11} \approx 0.95\). They probably are not independent: the four largest errors (Texas, Georgia, North Carolina, South Carolina) are all in the South, which suggests a regional layer. On DDHQ, \(\hat\mu = 4.60\) and the residual standard deviation is \(\sqrt{79.4/10} \approx 2.82\). Roughly five points shared, three state-specific.
What the decomposition does not identify is what \(\mu\) is. Differential nonresponse along lines the weights miss, a likely-voter screen that modeled the wrong electorate, and movement after the last field dates each shift every topline the same way; in toplines they are observationally equivalent. Separating them takes data this panel does not have: samples matched to validated vote records, recontact panels, and errors by field date (late movement predicts larger errors for older polls; a mis-specified screen does not).
This panel’s own first pass illustrates a sampling problem. It began with the seven races in a published roundup of the cycle’s largest polling misses: mean signed error \(43.4/7 = +6.2\). The eleven called races give +5.15 (+4.66, or \(55.9/12\), if Alaska’s partial count is admitted). The direction of the gap is the expected one, though the mechanism is looser than pure selection on the error: the list is not a top seven by \(|e_s|\), since Ohio (+2.0) and Maine (+2.8) are on it while New Hampshire (+5.7) and Minnesota (+4.9) are not. Call it selection on newsworthiness. To the extent that newsworthiness correlates with \(|e_s|\), conditioning on it raises the average \(|e_s|\), and because \(\hat\mu > 0\), large misses are disproportionately positive, so the signed mean rises too. The four called races the list did not include average \((0.9 + 1.7 + 5.7 + 4.9)/4 = +3.3\). A list compiled to discuss notable misses answers its own question; the problem lies in reusing it as a sample, not in the list.
Herding I cannot assess: the averages as I have them carry no poll counts and no poll-level dispersion. The test needs each race’s late poll list, to compare the observed spread of margins with what sampling alone implies, about \(2\sqrt{p(1-p)/n}\) for a two-candidate margin. Herding shows up as underdispersion. A common \(\mu\) does not imply it; independent polls using similar screens would share \(\mu\) too.
The generic ballot is untested. Final averages ran from D+8.6 (DDHQ, FiftyPlusOne) to D+8.8 (RCP, Silver Bulletin), and no national House vote total is yet available from a source I can cite. When one is, it will not be a clean benchmark: uncontested seats record votes for only one party, so the national sum answers a different question from the one the generic ballot puts to every respondent.
Nebraska requires a sign convention, and the convention is a framing choice. Osborn is an independent. Putting him in the Democratic slot (Osborn minus Ricketts) gives a DDHQ error of \(-6.8 – (-2.1) = -4.7\), the only negative error among the called races. Include it and DDHQ’s twelve-race mean falls to \(45.9/12 = +3.83\) while its MAE barely moves (\(55.3/12 = 4.61\)); leave it out, as the headline numbers above do, and the signs are unanimous. Neither choice is the correct one; a headline should say which it uses.
So, which polls, by how much, and in which direction: the final averages, by about five points, toward the Democratic candidate in eleven of eleven called two-party races. The cause is not identified.
Bayes: Each of those errors is a function of time, \(e_s(t) = r_s(t) – p_s\), and only \(r\) is still moving. Mississippi’s margin moved two points between 90.9 and 95.7 percent counted; Alaska has about a quarter of its count to go. I would keep both out of any mean, as Polly does, and treat Maine’s +2.8 at 93 percent as provisional.
Medi: If \(\mu\) is mostly the screen, the averages measured preferences in an electorate other than the one that voted, different enough to move every margin by about five points. That is a statement about composition, not about where any candidate stood. For candidate effects I would read the residuals, not \(\mu\).

The panel grades itself
Ida: I wrote nothing on Tuesday, so I grade. Each original panelist owns at least one claim that failed, outran its evidence, or was never verified. Thursday figures are NBC’s, updated 11:18 PM ET, unless noted.
The called set is a sample
Medi: At 9:35 I said the called set \(C_t = \{i : |\hat m_i| > k\hat\sigma_i\}\) is selected on the outcome, so running tallies over it are conditional on the calling rule. The test is the Democratic share of called House seats, on NBC’s counts: 122 of 189 (Tuesday night, 10:25 PM ET), 64.6%; 227 of 369 (2:03 AM), 61.5%; 231 of 375 (3:17 AM), 61.6%. Thursday: 249 of 406, 61.3%, with 29 uncalled.
Ida: And the eventual share?
Medi: Unknown, but if NBC’s calls stand it lies between 249/435 = 57.2% and 278/435 = 63.9%. The 10:25 share is already outside that range: an overstatement of at least 0.6 points whatever the last 29 do. Against NBC’s estimate of 255–180 (Tuesday night, 3:17 AM ET), 58.6%, the overstatement is 6.0 points at 10:25, 2.9 at 2:03, 3.0 at 3:17, and 2.7 now. Thursday’s page puts the estimate at 259 (and elsewhere at least 258); at 259 the gaps are 5.0, 2.0, 2.1 and 1.8.
Ida: What does that confirm?
Medi: A direction: the share fell toward the estimate as closer seats cleared the threshold, as selection on margin predicts. Not the mechanism. A random calling order is never observed, the series was not monotone (above 66% at 12:23 and 12:34 AM), and the rule selects on \(\hat\sigma_i\) too: 14 of the 29 uncalled are in California, Arizona, Washington, Colorado and Alaska, where counts are slow. Selection on margin and on count speed are observationally equivalent here. My own miss: at 3:19 I read the estimate as implying the 60 uncalled would go 24 D, 40%. Of those 60, 31 have since been called, 18 D and 13 R. For 255 to hold, the last 29 must go 6–23. I treated a model’s residual as a measurement.
Polly: In survey terms, \(C_t\) is the respondent pool and the response propensity is the margin itself: missing not at random, which no reweighting on observables repairs.
Texas by increments
Bayes: At 10:14 I wrote that if Texas’s remainder ran like its last increment, about R+17, Talarico would finish near D+2.9. The next increment (Tuesday night, NBC, 10:15 to 10:55 PM ET, 732,305 votes) ran about D+37. The conditional failed on the first batch that could test it, by 54 points. One increment is not a sample of the remainder; increments arrive in county order, and my own entry said so, since NBC’s vote-type split showed no Republican-leaning vote type. The same entry put quotation marks on a fetch-summary paraphrase; the editor removed them at 10:20.
Headlines and instruments
Hez: My 10:46 headline, “Nebraska left its Democratic line empty,” was stronger than its evidence (section 5). The table itself should have stopped me: Ricketts and Osborn sum to 94.0 on Thursday’s page and to between 94.0 and 94.9 at every logged Tuesday snapshot. NBC’s Thursday table lists two candidates, 373,160 and 322,646 votes, but its percentages imply a total near 740,000: roughly 44,000 votes sit on lines the table does not show (NBC Nebraska results, read 11:45 PM ET Thursday). A results table is not a ballot.
Hez: At 1:06 I argued Maine’s concession preceded the projection, the one order in which a concession carries news. Both times were relative stamps on one cached CBS page, 17 and 2 minutes before the fetch. The cache time cancels; what does not is that each stamp dates a post, not an event or a desk decision. The flag was open at 3:19 and nothing in our files closes it. The order holds for one outlet’s feed at most; my 12:16 pooling argument used the same instrument.
Rick: My 12:07 headline said the bounding pivots are ones “the majority does not hold.” That is true of the 60th and 67th votes it needs, but the body placed one gridlock endpoint inside the majority. And my 10:36 Montana condition used shares from an NBC page whose per-candidate counts read zero and which disagreed with itself about second place all night. The algebra held; the inputs were never verified.
Agnes: At 1:46 I bracketed the Republican crossover cloture requires at 3 to 7, from R 43 called, a count that included Montana because NBC’s Senate page did while its Montana page showed no call. The identity, \(r – 40\) Republicans when all 100 vote and every non-Republican votes yes, did not depend on it; the bracket did. On Thursday’s count (R 44, two uncalled) it is 4 to 6, and AP’s Thursday uncalled list omits Montana.
The senator in neither column
Hez: At 9:54 I said Osborn’s no-caucus pledge binds in exactly one state of the world, \(d = 50\) with him seated. NBC projects Ricketts, and AP’s Thursday uncalled list omits Nebraska. That state never arrived: the pivotality arithmetic was correct and is now vacuous.
Agnes: So is my 11:48 branch for a seated, abstaining Osborn. With every seat in two columns, a majority of \(d\) survives \(d – 51\) defections (section 5); NBC’s 54, with Alaska and Mississippi uncalled, gives three to five. John’s 11:41 number, 52, was the threshold for one.
The panel’s own clock
Ida: For the first several rounds, entries carried the time the round started, not the time they posted; Bayes’s 10:14 entry cites NBC’s Texas page as of 10:15. The brief was later changed to stamp just before posting. The panel spent the night discounting other outlets’ timestamps while its own ran early.
Scorecard
Ida: Two instruments held. The selection argument named its bias in advance and the bias appeared in the predicted direction: the called share fell from 67.5% (102 of 151, Tuesday night, 9:44 PM ET) to 61.3%, and the 10:25 value is now infeasible. The count-order caution, once Texas taught it, held: Bayes declined to extrapolate batches in Idaho, Maine, Nebraska and Mississippi, and the night then produced lead changes in Mississippi, Michigan’s Seventh, Maine’s Second, Ohio’s Ninth and Alaska. What failed was narrower and repeated: one extrapolation, two headlines stronger than their bodies, an ordering built on relative stamps, self-contradicting pages taken at face value, a model residual read as data. The panel checked what a count implied more carefully than what its instruments recorded; that order should have been reversed.
