Democratic Rep. Susie Lee defeated Republican Marty O'Donnell in Nevada's 3rd Congressional District, according to a race call by The Associated Press shortly after 4 a.m. Eastern time. Lee received 60.1% of the vote to O'Donnell's 37.8% with 65% of ballots counted at the time of the call.

Why it matters

The margin reflects a Democratic hold in a district Trump carried in the 2024 presidential election, where Lee had secured reelection with about 51.4% of the vote. Safety and Affordability PAC canceled $1 million in television reservations supporting O'Donnell shortly before the election.

With 65% of ballots counted, Lee led 60.1% to 37.8%, a significant gain over her 51.4% share in 2024. The remaining ballots were not included in the call, so the final margin may shift.

The players

Susie Lee

Susie Lee is the Democratic U.S. Representative for Nevada's 3rd Congressional District, serving since 2019.

Marty O'Donnell

Marty O'Donnell is the Republican nominee who won his party's June primary with Trump's endorsement.

Safety and Affordability PAC

Safety and Affordability PAC is a political action committee that reserved advertising to support O'Donnell and is financially backed by MAGA Inc.

The details

Lee has represented the district since 2019 and raised $1.2 million in the third quarter and $5.6 million for the cycle. O'Donnell won the June Republican primary with Trump's endorsement, and Safety and Affordability PAC, financially backed by MAGA Inc., had reserved $3 million in television advertising for him before canceling $1 million in reservations.

2019: Susie Lee began representing Nevada's 3rd Congressional District.
2024: Trump carried the district, and Lee secured reelection.
June: O'Donnell won the Republican primary with Trump's endorsement.
November 4, 2026: Lee was called the winner shortly after 4 a.m. Eastern time.

Season Trajectory

Lee's 60.1% share is well above her 51.4% in 2024, despite Trump having carried the district that year. The shift coincides with Trump-aligned groups reducing spending in some difficult-to-win House races.

Voters in Nevada's 3rd District now have Lee as their representative for the next term, with the final count still pending. Campaign spending decisions by outside groups can shape which races receive advertising in the closing weeks.

The takeaway

Late-cycle spending decisions by outside groups can significantly affect how competitive a district appears to voters. Watching final vote totals rather than early calls shows how a race changes as the remaining ballots are counted.
