Incumbent Democrat Gary Peters' decision not to seek re-election has opened Michigan's Senate seat, drawing a crowded Democratic primary led by Abdul El-Sayed's recent surge to 28% in a May 1-7 Mitchell Research poll over Rep. Haley Stevens (18%) and state Sen. Mallory McMorrow (17%), while ex-Rep. Mike Rogers dominates the GOP field. General election hypotheticals remain tight, with RCP averages showing Rogers edging El-Sayed (+3.5%) and McMorrow (+1.6%) but trailing Stevens slightly (-0.6%), per late April Glengariff data. Trader consensus at 73% for Democrat reflects perceived Democratic strength after their May 5 special state Senate win in a battleground district, despite polling toss-ups and August 4 primaries ahead.
