Chance of winning over time

Daily reruns of the model

Each day is a fresh run of today's model using only the polls that had finished by the day before. Daily runs since Jul 1.

How the forecast is built

Fundamentals D+11.6. Governor races follow a state's partisanship only about half as closely as federal races, and incumbents carry a much bigger edge (both fit on the 2018 and 2022 results). The fundamentals average half the state's lean plus the national environment (D+8.7) and 10 points for the incumbent with the eight published ratings.

Polls D+8.4. 11 polls, adjusted for house effects and likely-voter screens. Polls carry about 89% of the weight.

Polling errors here move with the same state's Senate race and with similar states.
