Las Vegas, Wednesday, 4 November 2026.
Democrat Susie Lee secured a fifth House term Wednesday, defeating video game composer Marty O’Donnell in a key swing district previously carried by Donald Trump.

Race Outcome and Margin of Victory

Democrat Susie Lee secured a fifth term in the U.S. House of Representatives on Tuesday, November 3, 2026, defeating Republican challenger Marty O’Donnell in Nevada’s highly competitive 3rd Congressional District. The Associated Press declared Lee the winner at 4:04 a.m. EST on Wednesday, November 4, 2026 [1][5][8]. Lee’s victory margin underscored the district’s status as a perennial swing district, where she previously won by (2.7% margin in 2024) in the 2024 election [4].

Political Significance of Nevada’s 3rd District

Nevada’s 3rd Congressional District, which includes western and southern Las Vegas Valley communities and areas south to Laughlin, has emerged as a critical battleground in national politics. The district, which President Donald Trump won in 2024, was rated as a likely Democratic seat by the nonpartisan Cook Political Report heading into the 2026 midterms [4]. This outcome reinforces the district’s role in shaping federal legislative agendas, particularly on fiscal policy, renewable energy incentives, and regional taxation frameworks that impact business operations across the Mountain West [GPT].

Candidates and Campaign Dynamics

Incumbent Rep. Susie Lee, first elected in 2018, campaigned as a moderate with a bipartisan record, emphasizing her experience in a district that demands cross-party collaboration [1]. Lee, who has served in the House since 2019, faced a well-funded challenge from Marty O’Donnell, a retired composer best known for his work on the Halo video game series [4][8]. O’Donnell, who received an endorsement from Trump during the Republican primary, positioned himself as a conservative alternative in a district where economic diversification and gaming industry policies are pivotal issues [1][8].

Implications for the 118th Congress

Lee’s reelection preserves the Democratic hold on the seat, maintaining a delicate balance of power in the U.S. House as the 118th Congress convenes. The Nevada 3rd District’s role in influencing federal economic and energy policies—particularly those tied to renewable energy tax credits and infrastructure funding—positions Lee as a key voice in shaping legislative outcomes that affect Nevada’s business ecosystem, including tourism, technology, and renewable energy sectors [GPT]. With Lee’s victory, Democrats retain a strategic foothold in a district that has historically seen narrow margins and high-stakes electoral battles [4][8].
