Incumbent Democratic Representative Susie Lee holds a strong position in Nevada’s 3rd Congressional District, a swing seat covering suburban Las Vegas areas that last elected a Republican in 2014. Lee secured the Democratic nomination in the June 9 primary and enters the November 3 general election after winning by roughly three points in both 2022 and 2024. Multiple nonpartisan forecasters, including the Cook Political Report, Inside Elections, and Sabato’s Crystal Ball, rate the race Lean Democratic. Republican nominee Marty O’Donnell, who won his June primary, faces the challenges of targeting spending in a shared expensive media market and overcoming the district’s modest Democratic tilt in voter registration and recent results. These structural and historical factors underpin trader consensus on the current probabilities.
