Mike Thompson leads the CA-04 House race at 69.5% in trader consensus, with Eric Jones at 29.5%, reflecting the incumbent Democrat’s 41% primary finish and 14-term tenure against Jones’ 22% showing in the June 2, 2026, top-two contest. Redistricting added rural, more conservative counties including Sutter, Yuba, and Colusa, yet the seat retains a strong Democratic tilt per forecasters. Thompson benefits from established party endorsements, committee influence, and voter familiarity in core Napa and North Bay areas. Jones, a self-funded progressive newcomer, gained ground through a late-August 2026 endorsement from eliminated Republican Ray Riehle, who launched outreach targeting GOP and independent voters, alongside debate challenges across all nine counties. The November 3 general election remains the decisive event, with limited late shifts noted in current pricing.
