Sen. Gary Peters of Michigan announced he will not seek re-election in 2026, creating a competitive Senate race. At 66, Peters’ decision to step aside after two terms is a surprise, as it challenges Michigan Democrats during a turbulent period. With the state’s 2026 Senate and gubernatorial contests on the horizon, the party may face difficult decisions over where to focus its resources. Peters, a moderate who previously chaired the Senate Homeland Security Committee, emphasized he’s not retiring but simply passing the reins. His exit adds pressure on Democrats, especially after Trump’s win in Michigan in 2024. Former U.S. transportation secretary Pete Buttigieg is a likely contender for the seat. This development, along with Governor Whitmer’s term limit, intensifies the upcoming political battles in Michigan.
