Wisconsin’s 3rd congressional district features a tight rematch between Democratic challenger Rebecca Cooke and Republican incumbent Derrick Van Orden ahead of the November 3 general election. Van Orden won the seat by roughly three points in 2024 after flipping it from long-term Democratic control, and recent polls show the candidates separated by low single digits or statistical ties. Forecasters rate the contest a toss-up, reflecting the district’s swing character, balanced fundraising, and voter priorities on local economic issues such as data-center development. With both candidates unopposed in their August primaries and three weeks remaining, small shifts in turnout among rural and suburban voters or late campaign events could determine whether the final margin falls into the narrowest buckets or widens modestly.
