2024 United States Senate election in Wisconsin

The 2024 United States Senate election in Wisconsin was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Wisconsin. Incumbent Democratic Senator Tammy Baldwin won re-election to a third term by a narrow 0 % margin, defeating Republican nominee Eric Hovde. Third-party candidates Phil Anderson and Thomas Leager were seen as potential spoiler candidates for Hovde in a state that had voted for Republican presidential nominee Donald Trump. This was the first time that Wisconsin voted for candidates of different political parties for U . senator and president since Democrat Gaylord Nelson was reelected as Republican Richard Nixon carried the state in 1968. The closest of Baldwin's three Senate victories, the race held similarities to Republican Ron Johnson's narrow win in 2022, down to the percentage and raw vote margin by which the incumbents won. It was the closest Senate race in the state since 1914 and the closest election ever for this seat. Baldwin won only about 4,000 votes more than Kamala Harris, while Hovde received about 55,000 fewer votes than Trump. This likely means that some Trump voters voted for Baldwin or a third-party candidate. While almost all of the state's counties swung Republican compared to Baldwin's 2018 victory, Baldwin improved in Waukesha and Ozaukee. The primary election took place on August 13, 2024. The election was considered essential for Democrats' chances to retain the Senate majority in 2024.
