Recent polling in Wisconsin’s 1st District shows a statistical tie between Republican incumbent Bryan Steil and Democratic challenger Mitchell Berman, with the most recent surveys from House Majority PAC and DCCC Analytics placing the candidates within one point. This closeness has prompted Cook Political Report to shift its rating from Likely Republican to Lean Republican and led the DCCC to add the seat to its Red-to-Blue program. Steil has spent heavily on advertising, yet Trump’s job approval remains underwater locally. These factors keep margin-of-victory markets balanced around narrow outcomes, with traders assigning the highest probabilities to Republican or Democratic edges under 6 points. The November 3 election remains the key upcoming catalyst.
