Incumbent Bryan Steil holds a clear edge in Wisconsin’s 1st Congressional District race, reflecting the seat’s long Republican history, his established fundraising advantage exceeding $5 million, and voter familiarity in a district Trump carried narrowly in 2024. Democratic challenger Mitchell Berman, an emergency room nurse and first-time candidate, has gained ground through DCCC Red to Blue inclusion, which provides added resources and visibility, alongside recent polling showing near ties or single-digit margins. Cook Political Report shifted its rating to Lean Republican in late September, citing Democratic momentum, though other forecasters maintain Likely Republican assessments. Steil’s campaign has countered with substantial ad spending attacking Berman’s positions on immigration and spending, while the November 3 general election remains the decisive contest.
