**Incumbent Democrat Susie Lee secured her party's nomination in the June 9, 2026 primary with roughly 69% of the vote, facing Republican nominee Marty O'Donnell in the November general election for Nevada's 3rd congressional district.** This western Las Vegas-area seat carries a D+1 partisan voting index and has been rated Lean Democratic or Likely Democratic by major forecasters. Lee has held the seat since 2019 and prevailed in narrow 2022 and 2024 general elections. The current trader consensus around 89.5% for Democrats reflects the incumbent's established position, fundraising edge, and the district's modest Democratic tilt, while Republicans remain optimistic about potential coattails from the statewide gubernatorial race. The November 3, 2026 contest remains the key resolution trigger.
