State Rep. Donavan McKinney leads the Democratic primary for Michigan’s 13th Congressional District, scheduled for August 4, 2026, with trader consensus assigning him the highest probability at 56.5%. McKinney, a sitting state representative, has secured key progressive endorsements, including from the Working Families Party, and leads in fundraising and local media coverage as of May 2026. Incumbent Rep. Shri Thanedar trails at 33.5% amid reports of criticism over his donor base and issue positioning. The remaining candidates—Shelby Campbell, Anthony Carbonaro, and Nazmul Hassan—hold single-digit shares consistent with limited visibility and resources. Recent developments center on McKinney’s established district presence and organized support network, which traders view as advantages heading into the primary.
