**Democratic incumbent Steven Horsford holds an 88% implied probability in the NV-04 House race, with Republican nominee Cody Whipple at 11%.** Horsford, first elected in 2018 and re-elected narrowly in 2024 with 52.7%, faces no Democratic primary opposition and benefits from substantial fundraising, labor and organizational endorsements, and the district’s D+1 to D+2 partisan lean that includes Democratic-leaning North Las Vegas suburbs alongside rural areas. Whipple, a telecommunications business owner, secured the Republican nomination in the June 9, 2026 primary with 61.8% but enters the general as a lesser-known challenger in a seat rated “Likely Democratic” by Cook, Sabato’s Crystal Ball, and other forecasters. Models project Horsford winning by roughly 10 points on fundamentals, though the district’s mix of urban and rural voters and Nevada’s recent rightward shift keep the contest on watch lists. The November 3, 2026 general remains the key resolution date.
