## Summary

Republican Michael Alfonso has won Wisconsin’s 7th Congressional District, beating Democrat Fred Clark by 12.2 percentage points with nearly all ballots counted. He will take the seat once held by his father-in-law, Transportation Secretary Sean Duffy, and become the youngest member of the House, marking a generational change in Congress.

Alfonso, who is married to Duffy’s eldest daughter, Evita, is a University of Wisconsin-Madison graduate who worked in construction and produced Dan Bongino’s podcast. He won a five-way Republican primary after receiving Donald Trump’s endorsement and support linked to $1 million from Duffy’s dormant campaign account, routed through a super PAC. Alfonso will succeed Tom Tiffany, who left the seat to run unsuccessfully for governor; Clark, a former state legislator and forester, called the race the district’s first real contest in 15 years.
