Michigan’s 2026 Senate contest is an open-seat race after Gary Peters’ retirement, and reporting describes the general election as likely close. On the Democratic side, Mallory McMorrow, Abdul El-Sayed, and Haley Stevens are in a competitive primary that’s becoming a proxy fight over the party’s future, shaped by fundraising, endorsements, and foreign-policy debates. The open-seat setup and “close” general-election expectations may keep odds tight and volatility elevated. Primary uncertainty on the Democratic side could add near-term uncertainty until the field clarifies.
