Marty O'Donnell, the award-winning composer behind the Halo franchise and a vocal critic of woke culture in the gaming industry, won the Republican primary in Nevada's 3rd Congressional District Tuesday, setting up a November showdown with well-funded Democratic incumbent Susie Lee.
O'Donnell captured roughly 44 percent of the vote in a four-way Republican primary held June 9, finishing nearly 20 points ahead of runner-up Tera Anderson, according to results reported by the Las Vegas Review-Journal and the Nevada Independent. The margin was decisive, and it arrived after President Donald Trump and Nevada Governor Joe Lombardo both threw their full weight behind the 71-year-old composer-turned-candidate, effectively consolidating the field around him.
"Marty O'Donnell has my Complete and Total Endorsement to be the next Representative from Nevada's 3rd Congressional District," Trump wrote in April when he announced his backing. Lombardo followed with his own endorsement, calling O'Donnell the strongest candidate to unseat Lee in one of the most competitive congressional seats in the country.
O'Donnell built his reputation over three decades as the audio director and composer behind the Halo series at Bungie, one of the most commercially successful video game franchises in history, and later contributed to Destiny. His background puts him well outside the standard congressional candidate template, and he has leaned into it, connecting the political fight against progressive overreach to what he describes as the "wokification" of the gaming industry. "I believe the enthusiasm for the re-release of the original Halo is in large part due to the wokification of the gaming industry," O'Donnell wrote in a post on DEIDetected, arguing that entertainment and politics are intertwined in ways that voters are increasingly ready to act on.
The Nevada result adds to a string of primary wins by Trump-backed candidates in competitive House districts as Republicans work to protect and expand their narrow majority heading into November. The National Republican Congressional Committee added O'Donnell to its MAGA Majority program in late April, a designation that provides candidates in high-priority battleground races with strategic resources and national visibility, according to Roll Call. Nevada Republicans Carrie Buck and O'Donnell were both added to the program, signaling that the NRCC views the district as genuinely flippable.
Nevada's 3rd covers suburban Las Vegas and Henderson, the kind of turf that has swung between the parties as they competed for college-educated suburban voters. Trump carried the district in 2024, according to the NRCC, and the previous Republican nominee lost to Lee by roughly 10,000 votes, a margin strategists believe is closeable in a favorable national environment. O'Donnell himself ran for the same seat in 2024 and placed fourth in the primary. His turnaround this cycle, from also-ran to clear frontrunner, reflects the combined force of the Trump and Lombardo endorsements and a primary field that did not coalesce around any single challenger.
A Well-Funded Incumbent Awaits
Susie Lee won her own Democratic primary Tuesday and enters the general election as a formidable opponent. She raised $3.9 million for the 2026 cycle and reported more than $3.3 million in cash on hand as of late May, according to Federal Election Commission data cited by the Nevada Independent, a massive financial advantage over O'Donnell heading into the fall. Lee won reelection in 2024 by nearly three percentage points even as Trump narrowly carried the district, a split-ticket outcome that underscores her ability to hold suburban voters who otherwise backed the Republican presidential ticket.
O'Donnell's case against Lee will center on her alignment with national Democratic leadership, her record on spending and border policy, and the broader cultural argument he has been making since launching his campaign. The NRCC has already been producing opposition research on Lee, including criticism of her statements on Israel-related legislation. For his part, O'Donnell has framed his run around lower costs, border security, and reversing what he calls a culture of government overreach, themes that align tightly with the national Republican message this cycle.
The race is rated Lean Democratic by several forecasters, reflecting Lee's incumbency advantage and financial strength. But Republicans point to Trump's 2024 performance in the district as evidence that the underlying electorate is within reach. The general election is November 3. With House control potentially hinging on a handful of seats like this one, both parties will invest heavily in the contest. Whether a gaming industry veteran who spent his career scoring fictional battles can win a real one in the suburbs of Las Vegas is the question Nevada voters will answer in the fall.
