Recent polling and the Democratic primary outcome have positioned the party as the market favorite in this competitive Wisconsin rematch. Incumbent Republican Derrick Van Orden narrowly held the R+3 district in 2024, but a July survey showed Democratic nominee Rebecca Cooke ahead by four points in a head-to-head matchup. Cooke secured her nomination easily on August 11 after the primary, consolidating party resources for the general election on November 3. Forecasters rate the seat a toss-up or slight Democratic lean, reflecting its battleground status and voter responsiveness to national conditions. Traders appear to weigh these dynamics, along with the challenger’s momentum, more heavily than the incumbent’s structural advantages when pricing the outcome.
