In Michigan's 8th congressional district, an open seat after Rep. Elissa Slotkin's Senate bid, recent polls showing Democrat Kristen McDonald Rivet leading Republican Mike Rogers by slim margins—46%-44% in the October 23-25 Emerson survey and 48%-47% in the October 28-30 AtlasIntel poll—anchor trader consensus at 64.5% for a Democratic win. This battleground district, spanning Genesee County and leaning slightly Republican in presidential races, sees heavy GOP super PAC ad spending exceeding $10 million, yet polls indicate limited movement. National headwinds for Republicans and Rivet's state Senate experience bolster her edge, with final pre-election surveys and early voting trends as key upcoming catalysts.
