Incumbent Democrat Steven Horsford faces Republican nominee Cody Whipple in Nevada’s 4th congressional district on November 3, 2026. The district’s D+2 Partisan Voter Index and Horsford’s established incumbency since 2019 underpin the 87.5% implied probability for a Democratic victory reflected in current trader consensus. Horsford advanced unopposed in the June Democratic primary, while Whipple secured the Republican nomination with 61.8% of the vote. Nonpartisan forecasters including the Cook Political Report classify the contest as Likely Democratic, consistent with the district’s modest partisan tilt and lack of recent polling shifts that would alter fundamentals. Upcoming general-election dynamics, including turnout in Las Vegas suburbs and rural areas, remain the primary variables that could influence final margins.
