Gary Peters' retirement has opened Michigan's U.S. Senate seat for the November 2026 election, drawing a competitive Democratic primary among Haley Stevens, Mallory McMorrow, and Abdul El-Sayed alongside Mike Rogers as the likely Republican nominee. Recent primary polls show a tight three-way Democratic contest, while general-election matchups indicate leading Democrats competitive or ahead of Rogers in some surveys. The state's recent Democratic Senate performance, underlying partisan balance, and toss-up ratings from major forecasters contribute to trader consensus pricing a Democratic general-election victory at 68.5 percent, though the outcome remains sensitive to primary results, candidate positioning on economic issues, and suburban turnout in the months ahead.
