Tom Tiffany secured the Republican nomination for Wisconsin governor in the August 11, 2026 primary with roughly 95 percent of the vote after entering the race in September 2025 and receiving an early endorsement from President Trump in January 2026. That backing prompted his strongest potential rival to exit the contest immediately, leaving only minor candidates such as Andy Manske on the ballot. Tiffany also consolidated support from all of Wisconsin’s Republican members of Congress and benefited from the absence of a competitive field in an open-seat race created by incumbent Tony Evers’ retirement. Trader consensus at 100 percent for Tiffany reflects these developments and the primary’s decisive result. The only realistic paths that could still alter the outcome involve unresolved certification disputes, a successful recount petition, or a late legal challenge to ballot eligibility, though none have surfaced in the days since election night.
