Senator Gary Peters of Michigan announced he will not run for re-election in 2026, leaving an open Senate seat in a fiercely contested battleground state. After two terms in the Senate and three in the House, Peters, 66, stated it was time to pass the reins to the next generation. His decision presents a challenge for Michigan Democrats, especially after President Trump’s 2024 victory in the state. Potential candidates include former U.S. Transportation Secretary Pete Buttigieg, who recently moved to Michigan. Peters’ departure also adds complexity to the 2026 Senate race and upcoming gubernatorial contest in Michigan.
