Rebecca Cooke leads trader odds in the WI-03 House race due to the national midterm environment, where the president's party typically faces headwinds, combined with the district's competitiveness and Cooke's strong fundraising edge. Incumbent Derrick Van Orden won the seat by under 3 points in 2024 against the same Democratic opponent and carried it narrowly for Trump that year, but recent forecasts from outlets including Cook Political Report have shifted the rating to Lean Democratic. Democratic internal polling from mid-October showed Cooke ahead by a point, while her campaign outraised Van Orden substantially in the latest reporting period. With the November 3 election one week away, traders appear to weigh these factors and the broader push by Democrats to flip competitive House seats more heavily than scattered earlier polls.
