Elections in Montana |
---|
The 2024 United States Senate election in Montana was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Montana. Incumbent Democratic Senator Jon Tester lost re-election to a fourth term, being defeated by Republican nominee Tim Sheehy. Sheehy's victory gave Republicans control of both of Montana's Senate seats for the first time since 1911. Primary elections took place on June 4, 2024.[2] Although Tester outperformed Kamala Harris in the concurrent presidential election by 12.8 points, which was the strongest overperformance of any Democratic Senate candidate, it was still not enough to win.[3]
This race was one of two 2024 U.S. Senate races in which Democratic senators sought re-election in states where Republican Donald Trump won in both the 2016 and 2020 presidential elections, the other being Ohio. Tester's re-election was considered essential for Democrats' chances to retain the Senate majority in 2024.[4]
