David Crowley, the Democratic nominee and Milwaukee County executive who narrowly won his party's August 11 primary, holds an implied 75.5% probability in the Wisconsin governor race, while Republican nominee Tom Tiffany, a U.S. representative who secured his nomination with little opposition, sits at 23.5%. Trader consensus reflects Crowley's positioning as a moderate with broad appeal in a state where the prior Democratic incumbent declined to run for a third term, combined with an early August poll showing him ahead by 4 points. Tiffany's profile as a Trump-endorsed candidate from northern Wisconsin has not yet closed the gap in post-primary surveys. The November 3 general election remains months away, leaving room for shifts from turnout patterns in swing counties and any late developments in campaign messaging on shared revenue and state issues.
