Incumbent Democrat Dina Titus faces Republican state Sen. Carrie Buck in Nevada’s 1st congressional district on November 3, 2026. The seat, covering parts of Las Vegas and Henderson, carries a modest Democratic lean and was won by Titus by roughly eight points in 2024. Both candidates secured their party nominations comfortably in the June primaries and have raised substantial funds, with Buck drawing national Republican support including an endorsement from President Trump. Forecasters rate the race Likely Democratic, citing Titus’s incumbency advantage and the district’s underlying partisan makeup, while noting Buck’s profile as an educator and state legislator could keep the contest closer than in prior cycles. Trader pricing on victory margins clusters in the 10–20 point Democratic range, reflecting these fundamentals alongside uncertainty over turnout and any late-cycle national shifts.
