Incumbent Rep. Steven Horsford (D) secured the Democratic nomination for NV-04 without a primary challenge after candidate filing closed in March, bolstering trader consensus at 80.5% for a Democratic hold amid his strong 2024 general election win (52.7%) and the district's D+2 Partisan Voter Index. Cook Political Report rates the seat Likely D, noting low priority despite Kamala Harris's narrow two-point 2024 presidential margin here. Republicans face a crowded closed primary on June 9 featuring rancher Cody Whipple, attorney Ronda Kennedy, and Anthony Snowden, potentially fragmenting resources and producing a weaker general election nominee. Horsford's recent "Congressman on the Job" series and North Las Vegas AI workforce partnership enhance his visibility with key voting blocs.
