Who is forecasted today to win the Wisconsin governor's race?
Updated Tuesday, October 27, 2026 · 7 days to Election Day · VotePredictor
David Crowley is favored. The VotePredictor forecast gives Crowley a 72% chance of beating Tom Tiffany, with a predicted margin of Crowley +2.6. That is a Lean D race: Crowley wins about two times in three, and Tiffany in the other 28%.
What the forecast is built on
The forecast starts from the 3 public polls in the forecast window, whose plain average is Crowley +3.5. Each poll is corrected for its voter screen and its pollster's measured house effect first (the “Adjusted” column below).
- The polls, weighted and corrected, read Crowley +2.5.
- The fundamentals (the state's presidential lean, incumbency, the last result and the national environment) read Crowley +3.8.
- The published forecast blends the two, mostly on the polls, at Crowley +2.6.
Misses of a few points are common, so a 2.6-point lead is a 72% chance and not a lock.
