Former Transportation Secretary Pete Buttigieg is eyeing a potential bid to represent Michigan in the US Senate after Democrat Gary Peters announced Tuesday he would not seek a third term, leaving open one of the most competitive seats in the 2026 cycle.

Buttigieg, who was mayor of South Bend, Indiana, moved to his husband Chasten’s home state of Michigan in 2020 after losing to President Biden in the Democratic primary that same year.

U.S. Sen. Gary Peters announced this week he will not seek reelection, setting the stage for a potentially crowded 2026 race.
