Republican traders hold a slim edge at 53.5% for retaining Senate control post-2026 midterms, mirroring polling averages projecting a narrow 51-49 majority amid tight battlegrounds in Michigan, North Carolina, Maine, and Alaska. Recent early-May surveys show Republicans poised to flip the open Michigan seat while defending Ohio and Texas against Democratic challengers, offsetting projected Democratic pickups in North Carolina and Maine where incumbents Thom Tillis and Susan Collins face vulnerability. Inside Elections' April ratings shifts further solidified GOP leans in Ohio, Nebraska, and South Carolina. The race stays contested due to midterm headwinds for the president's party, historical incumbent advantages, and uncertain primaries; national economic trends or candidate scandals could tip the balance toward a Democratic path to 50-plus seats.
