Republican Michael Alfonso won Wisconsin's 7th Congressional District House seat, succeeding outgoing Representative Tom Tiffany, who ran for governor. Alfonso defeated Democrat Fred Clark, a former state representative, with 55.3 percent of the vote to Clark's 44.7 percent.

Alfonso is projected to become the youngest member of Congress, and his victory keeps the district in Republican hands in a region that leans red. The result also reflects the campaign's emphasis on a new generation of Republican leaders, with endorsements from President Trump and Transportation Secretary Sean Duffy.
