Why this race matters
This is the 22nd closest governor race in the forecast, 15.4 points, out of 36.
36 governor races are in the forecast (19 Democratic leads, 17 Republican leads). A governor's race does not decide control of Congress.
No incumbent is on the ballot.
No earlier forecast of this race is archived, so there is no previous projection, date, or reason to show.
History block in the model: R+22.0. That is the office blend, not one past election.
Last same-office result in the candidate file: 2022 R+13.7. A special on the 2026 ballot is not automatically that contest.
The polling block for this race was omitted.

Model
- Raw data
2024 presidential baseline
National R−D 1.5County presidential file. Not the 2026 result.
- Raw data
Generic ballot
D 51.7 R 43.1 R−D -8.6National Wikipedia aggregate, 2026-10-30. State generic ballots, where a public poll exists, are mixed with the national swing for a race that does not have its own poll: ME, MI, NH, NY, OH. A state with no generic-ballot poll keeps the national swing and is not assigned a neighbor's.
- Raw data
Party identification
Pew D+5 and Gallup D+10, blend R−D -7.3Pew 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%.
- Model input
National block
R−D -8.160% generic ballot and 40% party identification. The swing versus the 2024 presidential margin is what gets transmitted.
- Model input
Swing transmitted
0.40 × -9.5 = -3.8This race has its own poll. The swing in the history blocks, before they shrink toward that poll, is the national block minus the 2024 presidential margin. Elasticity is shrunk halfway toward 1.
- Model input
History block
R−D 22.2Weights 2018 5 / 2024 35 / 2020 20 / 2022 16. If that office was on the ballot in 2022, that year takes the 40 and 2018 takes the 5. Otherwise 2018 keeps the 40. A missing year is filled with the 2020 result for the same office. Another office is not used. The year lines are Oklahoma County, the largest county, not the state total: 2018 D+11.8 w5, 2022 open seat D+4.3 w16. No incumbent is on the ballot, so the 2022 result keeps 40 percent of its usual weight and 40 percent of its gap versus the 2024 presidential margin. The prior nominee's margin is not the open-seat baseline. The state number above is the vote-weighted sum. A 2024 county map is not copied forward unchanged.
- Model input
Electorate block
R−D 14.4History 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. That spread is ballot size, not the demographic file. 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.
- Model input
Turnout block
R−D 15.2Each 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.
- Model input
National environment
R−D 14.0History plus the full transmitted swing. With no poll of this race, that swing is the state generic ballot mixed with the national block, or the national block alone.
- Model input
State environment
R−D 14.9History plus 45 percent of the transmitted swing. This is a Senate and governor weight.
- Model input
State partisan lean
R−D 34.3The 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.
- Model input
Trump popularity
R−D -4.1New York Times approval average, October 29, 2026: 37.4% approve, 60.2% disapprove. Net approval -22.800000000000004. 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.
- Model input
Candidate favorability
R−D 0.0Open seat or no incumbent. Favorability is zero.
- Model input
Demographics
R−D 13.7One statewide block only. A county that is more college-educated or more nonwhite than the other counties in this race takes more of the transmitted swing, and a more rural county takes less. That changes this block, at its weight. It does not choose which counties move when the margin is spread back out. That spread uses ballot size. The shares are the 2012–2016 American Community Survey and the 2010 Census, from the 2018 county election-context file. Alaska is not in that file.
- Model input
Finance
R−D 15.5No sourced spending edge. The block is history, or history shrunk toward the poll. It is not a finance model.
- Model input
Issues
R−D 15.5No sourced issue score. Same treatment as finance. It is not a separate issue model.
- Model input
Polling
R−D 11.1Individual polls only, 8.6. No Wikipedia average row. Named support R−D 5.5. Allocated support R−D 8.6. Named support does not move. Only the undecided line is split, 58.7% Republican and 41.3% Democratic. That is the 2024 two-party Republican share 67.5 moved halfway to 50 and capped at 60/40. A minor-party line is not published as its own candidate. Banned individual rows excluded: 0. One same-office miss, 2022: the poll was R−D 4.8 and the result was 13.7, miss 8.9. A single cycle is noisy, so 40 percent is kept. Capped at 2.5 points. It is added to the polling term only. It is not a separate weight. Applied to the polling term: 2.50. Public pollsters: 1. Outliers: 0. 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. It is not in the average. 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. Pollster quality nudges that weight by only a few percent. The same rule is used on a House poll. House district polls are likely-voter polls only.
- Model input
Generic ballot weight
R−D 18.2The generic ballot stays in the blend next to the independent polls. It is not shrunk toward the poll and an internal does not replace it. Weight 9.5%.
- Model input
Top line
Not a House termSenate and governor are the top line. They are not moved by themselves.
- Model input
Candidate
R+0.00 added wholeOpen seat. No incumbency term. A negative popularity score is not added on top of the office baseline. No overperformance. An open seat, a scandal, or a missing incumbent gets none. These points are not watered down to the candidate weight. The candidate weight is a separate slice of the baseline. On a Senate or governor race with three public polls and no outlier, the points stop at that poll instead of moving past it.
- Model input
Scandal
NoneNo candidate on this ballot is scandal-defined.
- Model input
Endorsements
R−D +0.30Trump endorsed Mike Mazzei. The presidential lean here is R−D 34.3, so the endorsement helps 0.30. Ballotpedia, Endorsements by Donald Trump, 2026 tables, page updated August 5, 2026. A primary endorsement is counted when that person is the nominee. A lost primary, a candidate not on the ballot, and a withdrawn endorsement are not.
- Model input
Halfway floor
AppliedPresidential margin 34.3. A thin poll may not move the result more than halfway from the office baseline 22.2 to the polling term. Held at 16.7. One poll does not rewrite the race.
- Model input
Pooling
60% of the way from each history block toward the polling termThe office history and the state's partisan lean differ by more than 12 points, so the history blocks move 60% of the way to the poll. Lean, Trump popularity, and favorability are not shrunk.
- Model input
Prediction market
90% win probabilityMike Mazzei 90.1% is a win probability, not a vote share. Republican win probability 90.1 from Kalshi 89.5% Republican; Polymarket 90.8% 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 17.0, which leaves 14.0. It enters once, at 5.0%. The polling term is not nudged. Books under $10,000 and primary markets are ignored.
- Model input
State bend
NoneNot applied.
- Model input
State environment adjustment
R−D -1.5The 2022 statewide margin was R−D 13.7 and the 2024 presidential margin was R−D 34.3. The country moved 1.4 from that presidential vote to the 2022 House vote. Fifteen percent of the difference is kept, capped at 1.5, so the state environment is -1.5 on top of the national swing.
- Model input
Early vote
D+1.0Reported party on ballots already cast is D 42.1 R 45.1, a Republican lead of 3.0 points of every ballot. At 5 days before the 2022 election that lead was -13.8. The difference is D+10.8. Fifteen percent is kept, capped at 1, so D+1.0. This is registration on the ballots returned so far, compared with the same point in the last midterm, not a count of how anyone voted and not another model's estimate of the electorate. The four age groups on the file, youngest to oldest, are 3.7%, 8.0%, 27.2%, and 61.1%. That is the state's own report of who has voted. It is read next to the county demographics already in the model. It is not a second early-vote point, and it is not another model's estimate of the electorate.

Other ratings
R−D 10.6 at 3.0%Cook, Sabato, Inside Elections, and the other columns on the same published tables (Decision Desk HQ, RealClearPolitics, Split Ticket, FiftyPlusOne, The Economist, Fox News, Silver Bulletin). 7 ratings, average R−D 10.6. A toss-up is 0, tilt 1.5, lean 3.5, likely 7, safe or solid 12. If this race is already further to that side, the rating does not pull it back. Mixed in after everything else, at 3.0 percent. It does not replace the poll. A seat nobody has rated is left alone.
