The Michigan mansion
Why this seat
Whitmer is termed out and a credible independent candidacy is live, which is the rare case where a three-way split can decide a governorship outright.
State of the field
Open, with three-way risk the desk treats as real rather than as noise.
The test
A two-way Michigan race is a coin flip. A three-way race is decided by which major-party coalition the independent draws from, and that is not yet knowable.
The mansion model runs separately from the Senate one. It carries less of the presidential result into the race — 0.45 of a point per point, against 0.78 on the Senate board — and allows a wider miss per seat, because a governor's race turns on a personal vote a national baseline cannot see. Both numbers stand: the simulated one and the one the desk wrote first.

Democratic nominee wins
Open, three-way risk, and a state that has swung hard in both directions since 2016.
Nothing written on this page feeds that number. The method.
No candidate ledger is published for this seat. A ledger requires a completed first-party source pass — every candidate's own published policy pages, read on the same day, under identical headings and an identical word budget. Until that pass is done, printing a partial board would rate the campaigns that publish against the ones that have not, which is the asymmetry the Standard exists to prevent.
