The race, in brief
Michigan elects a governor on November 3, 2026. Democrat Gretchen Whitmer is term-limited; she won by 9.56% in 2018 and 10.53% in 2022, and the text gives her a net +26 approval as of September 2026. Trump carried the state by 1.42% in 2024 after Biden won it by 2.78% in 2020. Republicans have not won a Michigan gubernatorial election since 2014. The state profile gives a median age of 40.1 and a college share of 0.3.
The Democratic nominee is Secretary of State Jocelyn Benson, with Senate majority leader Winnie Brinks as running mate; she won the August 4 primary with 83.2% over Sheriff Chris Swanson. The Republican nominee is U.S. Representative John James, endorsed by Donald Trump, who won with 50.1% over Perry Johnson; his running mate is Jay DeBoyer. The Libertarian party disavowed its nominee Anthony Hudson in September, though his name remains on the ballot. As of August 24, 2026 Benson had raised $12,508,001 with $5,934,240 on hand, James $6,444,200 with $1,065,614.
All seven raters listed call the race D, including the Cook Political Report (July 12, 2026) and Decision Desk HQ (September 23, 2026). The text's polling average is Benson 48.5%, James 40.7%.

How it has voted for president
| Two-party margin | 2016 | 2020 | 2024 |
|---|---|---|---|
| President | R+0.2 | D+2.8 | R+1.4 |
A shift of 1.2 points toward the Republicans from 2016 to 2024. county returns summed; MEDSL county file (2016), an MIT-licensed county file (2020, checked against certified state results) and MEDSL precinct returns (2024). For a district split across counties this is an estimate, and where the state published the exact 2024 figure for these lines, that exact figure is the one the model uses.

Who is ahead, and by how much?
Two numbers because they answer two questions. The nowcast is where opinion stands; the election-day forecast is where it is likely to end up.
How likely is each to win?
Monte Carlo error is ±0.2 points. A change smaller than that is simulation noise rather than news, and this page will not describe it as movement.
How wide is the range?
Nowcast: 90% of simulations fall between -3.0 and +15.5 points. Election day: -4.1 to +18.4. The election-day interval is 4.0 points wider, which is the 33 days of movement still to come.
What is the uncertainty made of?
Total sd 7.15 points, made of race-specific polling error 48%, drift to election day 32%, correlated polling error 12%, latent opinion 8%. The decomposition is stored with the forecast rather than reconstructed, so a probability whose dominant input is a placeholder is visibly that.
What evidence is this built on?
30 polls, most recent 2026-09-23. 47% verified against a primary source.
What changed since the last run?
Shaded band is the 90% interval, line is the central estimate, positive is Jocelyn Benson ahead of Anthony Hudson. Over 15 stored forecasts the central estimate moved -0.4 points. There were 7 specification changes (marked on the axis) and no new polls arrived over this window — so every movement in this chart is a change to the model, not a change in the race.
Since 2026-10-01: margin +0.00 points, win probability +0.0 points, on +0 polls.
Not answered here: why it changed. Splitting a move into new polls, time and specification means re-running the earlier model against the later inputs -- two extra posterior fits -- so it is computed on a cadence (scripts/attribute_forecasts.py) rather than while you wait. This pair of runs has not been decomposed yet. The size of the move is shown; the cause is not guessed at.
How has this model done before?
Measured on 230 forecasts across 230 races in cycles 2016,2018,2020,2022,2024: mean absolute error 4.56 points, Brier score 0.0543. The nominal 90% interval contained the result 94% of the time, the 80% interval 84%, and the 50% interval 47%. Read that with care: a national polling miss moves every race in a cycle at once, so the sample size for a question about the intervals is 5 cycle(s), not 230 forecasts. Per cycle -- bias +1.644 pts; 2016: n=43 bias=+4.68 cov90=0.860; 2018: n=63 bias=-0.52 cov90=1.000; 2020: n=35 bias=+5.44 cov90=0.886; 2022: n=54 bias=-0.60 cov90=0.944; 2024: n=35 bias=+1.48 cov90=1.000.
