Transportation Secretary Sean Duffy’s son-in-law, Michael Alfonso, won the crowded Republican primary in Wisconsin’s 7th Congressional District.Alfonso, powered by President Donald Trump’s endorsement, had secured 48% of the votes when the Associated Press called the race at 10:16 p.m. with 40% of ballots counted. The district voted for Trump in 2024 by a more than 20-point margin, making Alfonso the odds-on favorite in November.

“Michael is the son-in-law of our GREAT Secretary of Transportation, Sean Duffy, and the wonderful Rachel Campos-Duffy, of FoxNews, one of the most popular (and talented!) anchors in all of Television,” Trump wrote on Truth Social earlier this year. “His family has been fierce advocates for our Movement to, MAKE AMERICA GREAT AGAIN!”

Alfonso faced four other Republicans in the primary: financial adviser Kevin Hermening, Ashley Furniture director Jessi Ebben, business owner Niina Threlfall-Baum, and real estate broker Don Raihala.
