Democratic U.S. Sen. Gary Peters, of Michigan, announced Tuesday that he will not run for a third six-year term in 2026 leaving an open Senate seat.

Democratic Sen. Gary Peters won’t run for re-election in Michigan in 2026, creating a pivotal open Senate seat in one of the most tightly divided battleground states in the U.S.

"After three terms in the House and two terms in the Senate, I believe now is time for me to write a few more paragraphs in my current chapter and turn over the reins," Peters said.
