Incumbent Democratic Senator Tammy Baldwin won re-election to a third term,[1] narrowly defeating Republican nominee Eric Hovde.

[2] This was the first time that Wisconsin voted for candidates of different political parties for U.S. 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 Ron Johnson's narrow win in 2022, down to the percentage and raw vote margin by which the incumbents won.

Incumbent Tammy Baldwin was first elected in 2012, defeating former governor Tommy Thompson by 6 percentage points.

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.
