Recent polling averages and forecasts have established Democrat Rebecca Cooke as the frontrunner in the Wisconsin 3rd congressional district rematch against Republican incumbent Derrick Van Orden, with traders assigning her a 73.5% implied probability. Multiple 2026 surveys show Cooke ahead by narrow margins in this competitive swing district that Trump carried by about 1.5 points in 2024. Campaign developments, including Cooke's cease-and-desist over Van Orden's AI-generated videos and ongoing disputes over debate formats, have drawn attention to negative tactics. The race remains rated a toss-up or lean Democratic by several forecasters, with fundamentals like midterm dynamics and local economic concerns shaping the current trader consensus ahead of the November general election.
