The 2026 United States Senate election in Michigan will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Michigan. Incumbent Democratic Senator Gary Peters declined to seek re-election to a third term.[1] Peters was first elected with 54.6% of the vote in 2014, and re-elected with 49.9% of the vote in 2020. Along with Georgia, this is one of two Democratic-held Senate seats up for election in a state that Donald Trump won in the 2024 presidential election.

Background

Michigan is considered to be a purple state at the federal and state level. It was also a top battleground state in the 2020 and 2024 presidential elections. The state backed Joe Biden by 2.8% and Donald Trump by 1.4%, respectively.[2]

Both parties have seen success in the state in recent years. Democrats control both of Michigan's U.S. Senate seats, all statewide executive offices, and the state senate. However, Republicans control the Michigan House of Representatives and hold a majority in Michigan's U.S. House delegation.[3] Republicans have not won a Michigan U.S. Senate race since 1994 and have not won this seat since 1972.[4]

As one of only two seats up held by a Democrat in a state that voted for Trump in 2024, Michigan is considered a key Senate battleground in 2026.[5][6]
