2024 United States Senate election in Wisconsin

The 2024 United States Senate election in Wisconsin will be held on November 5, 2024, to elect a member of the United States Senate to represent the state of Wisconsin. Primary elections will take place on August 13, 2024.

Incumbent two-term Democratic senator Tammy Baldwin was re-elected with 55.4% of the vote in 2018. She announced she would be running for re-election on April 12, 2023.

Background
No Republican has won this Class 1 senate seat since Joseph McCarthy in 1952. Incumbent Tammy Baldwin was first elected in 2012, defeating former governor Tommy Thompson by 6 percentage points. She was re-elected in 2018 by 11 percentage points.

The race is considered to be slightly favorable to Baldwin, despite Wisconsin's nearly even partisan lean, with most polls showing Baldwin to be the favorite to win.

Wisconsin is considered to be a purple state at the federal level, especially since there are both a Republican and Democratic senator representing the state. Wisconsin was also a top battleground state in the 2016 and 2020 presidential elections. The state backed the Republican candidate in 2016, and then the Democratic candidate in 2020, both by less than 1% and only a plurality.

Both parties have seen success in the state in recent years. Republicans control both chambers of the Wisconsin Legislature and hold a supermajority in Wisconsin's U.S. House delegation. Republicans also control the state's other senate seat. However, Democrats have seen success in statewide races, including in 2022, where incumbent governor Tony Evers overperformed expectations and won reelection to a second term, despite polls showing his Republican challenger as the slight favorite.
