Incumbent Democratic Representative Susie Lee holds a commanding position in Nevada’s 3rd Congressional District, a western Las Vegas suburban seat last won by Republicans in 2014. Traders reflect her strong primary performance, consistent fundraising edge, and backing from organized labor in a district rated Lean Democratic by multiple forecasters. Martin O’Donnell secured the Republican nomination after a competitive primary and received a presidential endorsement, yet faces structural headwinds including the district’s recent narrow Democratic margins. Heavy outside spending on both sides continues into the fall, with campaigns highlighting economic issues such as tourism and tax policy. Late developments including turnout shifts or national political changes remain the primary variables that could narrow the gap before the November general election.
