Rep. Tom Tiffany (R-WI) won the Republican nomination to be Wisconsin‘s next governor on Tuesday, besting long-shot candidate Andy Manske in the GOP primary to advance to the general election. Tiffany secured the primary win with 96.4% of the vote, while Manske trailed with 3.5% of the vote, according to the Associated Press as of Tuesday evening. Tiffany, endorsed by President Donald Trump, awaits the Democratic primary winner as he looks to take back the governor’s mansion from Democrats for the first time since 2019. Tiffany has held his northwest Wisconsin seat in the U.S. House since 2020, announcing his exit from the chamber to run for the statewide office in September 2025 to replace retiring Gov. Several GOP candidates had dropped their bids for the seat either after Tiffany entered the race or after Trump endorsed him, leaving Tiffany to take on Manske, a 27-year-old medical service technician.
