Democrat Rebecca Cooke holds a clear edge in the WI-03 House race per current trader consensus, driven by the district's narrow 2024 presidential margin, multiple late-spring and early-summer polls showing her ahead or tied with incumbent Republican Derrick Van Orden, and Cooke's August primary victory that consolidated Democratic support. The seat, which flipped Republican in 2022 and remained competitive in 2024, features low incumbent favorability readings and generic ballot trends favoring Democrats in available surveys. Forecasters rate the contest a toss-up or lean Democratic, with the November general election still two months away and subject to national midterm dynamics, turnout shifts, and any late campaign developments that could narrow or widen the implied probability gap.
