Michigan senior Sen. Gary Peters, a Democrat, announced on Wednesday that he will not be seeking reelection and intends to retire at the end of the 119th Congress. “I always thought there would be a time that I would step aside and pass the reins for the next generation,” said Peters, 66, who has represented Michigan in the U.S. Senate since 2014. “I also never saw service in Congress as something you do your whole life.”

Democratic Gov. Gretchen Whitmer is term-limited, and along with the contests over the coveted Senate seat and governor’s mansion, there will also be open races for state attorney general, secretary of state, and as many as three competitive U.S. House seats. Both chambers of the state’s closely divided legislature will be up for grabs in the 2026 midterm elections as well.
