Rebecca Cooke holds a strong lead in the WI-03 House race due to the district’s competitive fundamentals, Democratic targeting of the seat, and a national environment less favorable to Republicans than in 2024. The rematch pits the Democratic challenger against incumbent Derrick Van Orden, who won by under three points two years earlier in a district Trump carried by 1.5 points. Recent forecasts from Cook Political Report and others have shifted the race to Lean Democratic, citing Cooke’s fundraising edge—over $12.7 million raised versus Van Orden’s $9.1 million—and polling trends showing her ahead or even. A late-October debate highlighted differences on taxes, social programs, and foreign policy, while an AI deepfake controversy drew attention to campaign tactics. With Election Day five days away, prediction-market pricing reflects these structural and momentum factors.
