Jim Pillen · win probability, not a vote share

Raw data Checking polls.

The office baseline and the polling term disagree by more than 8 points, so the interval is widened. The market and the polls disagree by more than 15 points of win probability, so the market weight is cut in half and the interval is widened. The thin mark is the 95% interval. The thick mark is the 80%. The hairline is zero. 697,981 ballots, equal to the table.

Model

  1. Raw data

    2024 presidential baseline

    National R−D 1.5

    County presidential file. Not the 2026 result.

  2. Raw data

    Generic ballot

    D 50.8 R 42.6 R−D -8.2

    National Wikipedia aggregate, October 5, 2026. State generic ballots, where a public poll exists, replace a uniform national swing: ME, MI, NH, NY, OH. A state with no generic-ballot poll keeps the national number and is not assigned a neighbor's.

  3. Raw data

    Party identification

    Pew D+5 and Gallup D+10, blend R−D -7.3

    Pew NPORS 2026, identifiers plus leaners: Republican 43, Democratic 48. Gallup party identification plus leaners, first two quarters of 2026: Democratic 49, Republican 39. Pew is 55% of this blend and Gallup is 45%.

  4. Model input

    National block

    R−D -7.8

    60% generic ballot and 40% party identification. The swing versus the 2024 presidential margin is what gets transmitted.

  5. Model input

    Swing transmitted

    0.79 × -9.3 = -7.4

    Only the share of the national swing this state took in the last midterm is transmitted. Elasticity is shrunk halfway toward 1.

  6. Raw data

    2026 early vote

    21,696 reported cast

    21,696 ballots reported cast as of 10/7/2026: 19,780 mail returned and 1,916 in person. Day-1 early vote is a signal, not a statewide margin. Mail is a count of returns, not the 2024 mail share. Applications and ballots that were only sent are not in this count. A day-1 pace gap is not a statewide margin.

  7. Model input

    History block

    R−D 21.9

    Weights 2018 5 / 2024 35 / 2020 20 / 2022 40. 2020 and 2022 results for this office are included in every state that had those races, including blowouts. A 2022 election is weighted ahead of 2018. If that office was not on the ballot, the 2020 result for the same office fills the year. Another office is not used. 2018 R+38.3 w5, 2022 R+44.5 w40. This is the last result for the office, not the presidential margin. A 2024 county map is not copied forward unchanged. A 2018 model error is not used.

  8. Model input

    Electorate block

    R−D 13.4

    History reweighted by usual midterm turnout, plus half of the transmitted swing. Rural and presidential-only counties still move farther when the result is spread back to counties. Published ballots are the 2018 midterm canvass for this office, split by these modeled shares. They are not the 2024 presidential vote. The 2026 early-vote count is not inside this margin.

  9. Model input

    Turnout block

    R−D 15.8

    Each county is weighted by its 2018 ballots divided by its 2024 presidential ballots. Small counties shrink halfway toward the state median. 2020 mail shares are not used. 21,696 ballots reported cast as of 10/7/2026: 19,780 mail returned and 1,916 in person. Day-1 early vote is a signal, not a statewide margin. Mail is a count of returns, not the 2024 mail share.

  10. Model input

    National environment

    R−D 10.9

    History plus the full transmitted swing from the 60/40 national block.

  11. Model input

    State environment

    R−D 13.6

    History plus 45% of the transmitted swing.

  12. Model input

    State partisan lean

    R−D 20.6

    The 2024 presidential margin of this state, or of this district for a House race. It is heavier than the old state-environment block and is not shrunk toward the polling term.

  13. Model input

    Trump popularity

    R−D -4.1

    New York Times approval average, October 7, 2026: 37% approve, 60% disapprove. Net approval -23. That is not a vote share. Four-tenths of the net is a margin, then scaled by this place's partisan lean (factor 0.45), so an unpopular president costs more in a Democratic state.

  14. Model input

    Candidate favorability

    R−D 0.5

    Jim Pillen's record minus this place's partisan lean is R+1.3. Thirty-five percent of that gap, capped at 5, is the favorability term, R+0.5. The old margin is not reused.

  15. Model input

    Demographics

    R−D 9.4

    County college, rural, and nonwhite shares from the 2018 election-context file change how much of the swing a county takes. No separate microdata file.

  16. Model input

    Finance

    R−D 15.7

    No sourced spending edge, so the block starts on history. With a poll, it shrinks toward the polling term with the other non-poll blocks.

  17. Model input

    Issues

    R−D 15.7

    No sourced issue score. Same treatment as finance.

  18. Model input

    Polling

    R−D 4.3

    Individual polls 3.5 (80%) and the Wikipedia average 7.3 (20%). Named support R−D 3.5. Allocated support R−D 4.3. Named support does not move. Only the undecided line is split, 55.2% Republican and 44.8% Democratic. That is the 2024 two-party Republican share 60.4 moved halfway to 50 and capped at 60/40. A named third-party vote stays third-party. Banned individual rows excluded: 1. State miss shrunk 40% toward zero: 0.00. Public pollsters: 2. Outliers: 1. Recency half-life 16 days. Sample weight n/(n+350). A registered-voter poll is 0.90. An internal poll, or a poll sponsored by one party, is weighted 0.20, and only when a public poll is also in the race. An internal-only file is dropped. A poll that names both parties is not an internal. A poll more than 8 points from the median of the others is cut in half.

  19. Model input

    Candidate

    R+4.50 reaches the result

    Jim Pillen gets a governor incumbent term of 4.5. Job-approval net is +11. That is solid, so the term is 4.5 points. Overperformance is a separate term and is not added again here. Jim Pillen's 2022 race is already in the history block, so it is not applied again.

  20. Model input

    Halfway floor

    Applied

    Presidential margin 20.6. A thin poll may not move the result more than halfway from the office baseline 21.9 to the polling term. Held at 13.1. One poll does not rewrite the race.

  21. Model input

    Pooling

    35% of the way from each history block toward the polling term

    Otherwise the shrink is 35%.

  22. Model input

    Prediction market

    89% win probability

    Jim Pillen 89.5% is a win probability, not a vote share. Republican win probability 89.5 from Kalshi 89.4% Republican; Polymarket 89.5% Republican. A price of 50 is a tie. Each point above 50 is 0.35 margin points, capped at 12, so the raw margin is 12.0. That margin is shrunk 40% toward the pre-market margin 17.6, which leaves 14.2. It enters once, at 2.5%. The polling term is not nudged. The market and the polls differ by more than 15 points of win probability, so the weight is half of 5% and the interval is wider.

  23. Model input

    State bend

    None

    Not applied.

  24. Model input

    Weights

    polling 21.0% · history 7.7% · candidate 7.6% · electorate 4.8% · stateEnv 4.8% · national 4.8% · turnout 2.8% · demographics 2.8% · finance 2.0% · issues 2.0% · stateLean 15.3% · trump 11.5% · favorability 10.5% · market 2.5%

    History is lighter. State partisan lean, Trump popularity, and candidate favorability are their own terms. A market, when it qualifies, scales every other weight and is not taken out of polling alone.

  25. County-sum margin

    17.5

    This is the sum of the reporting units after each unit moved off its own history. It is not the poll average.

  26. 80% interval

    6.9 to 28.2

    10th to 90th percentile of 50,000 draws. Poll, national, state, turnout, and candidate error.

  27. 95% interval

    1.2 to 33.8

    2.5th to 97.5th percentile. Senate and governor state errors in the same state share a correlation of 0.30. The band shown is the marginal interval.
