Incumbent Bryan Steil holds a 64% implied probability in trader consensus for Wisconsin’s 1st Congressional District, reflecting the seat’s Republican lean and his established fundraising edge exceeding $4 million in recent cycles. Mitchell Berman, an emergency room nurse and Democratic primary winner, sits at 36.5% amid national party support through the DCCC’s Red to Blue program and three October polls showing the race within one point. The Cook Political Report recently shifted its rating to Lean Republican. Heavy outside spending by Republican-aligned groups and the district’s history of GOP victories since the 1990s continue to anchor Steil’s position ahead of the November 3 general election, despite Democratic efforts to capitalize on narrower margins from 2024.
