Incumbent Democrat Susie Lee secured her party's nomination in the June 2026 primary and enters the November general election with strong positioning in Nevada's 3rd District. Multiple nonpartisan forecasters rate the race Lean Democratic, reflecting the district's D+1 to D+2 partisan voter index and Lee's narrow but consistent victories in 2022 and 2024. Republican nominee Marty O'Donnell, who prevailed in his June primary, faces structural challenges in a seat that has not elected a Republican since 2014. Comparable fundraising between the candidates and the district's suburban Las Vegas dynamics have kept the contest competitive on paper, yet trader consensus assigns Democrats an implied probability above 89 percent based on historical margins and current ratings. The November 3 outcome will help determine House partisan balance.
