Wyoming Republicans chose Rep. Harriet Hageman on Tuesday as their nominee for the U.S. Senate seat being vacated by retiring Republican Sen. Cynthia Lummis, who announced she would not seek a second term after winning election to the upper chamber in 2020.
Hageman defeated four other candidates in the five-way Republican primary: former Kirby Mayor Sam Mead, Jill Edwards, John Holtz and former environmental services business owner Jimmy Skovgard. She enters the race as the best-known and best-funded candidate in a state that ranks first nationally in percentage of registered Republicans.
President Donald Trump endorsed Hageman after previously backing her successful 2022 campaign to unseat former Rep. Liz Cheney in Wyoming's Republican House primary, which brought her national prominence. Now serving her second term as Wyoming's lone U.S. House member, Hageman is seeking promotion to the Senate.
What the Left Is Saying
Critics of Hageman's candidacy point to what they describe as a consolidation of power within the Republican Party around former President Trump. Cheney became Trump's most prominent Republican critic after she served as one of only two Republicans on the House Committee investigating the January 6 Capitol riots, alongside Rep. Adam Kinzinger, R-IL.
Progressive commentators have argued that Hageman's rise represents a broader trend of purging moderates from the GOP. "The removal of Cheney shows what happens to Republicans who cross Trump," wrote one political commentator on social media. The ousted Wyoming congresswoman is the daughter of former Vice President Dick Cheney, whose own political legacy was upended by his daughter's opposition to Trump's election denial.
Democratic groups have signaled they will contest the race but acknowledge the difficulty in a state with such deep Republican roots. The Democratic nominee will face long odds against Hageman in November's general election.
What the Right Is Saying
Trump endorsed Hageman, calling her a "true conservative" who will fight for Wyoming values in the Senate. The endorsement proved decisive in the primary, where Hageman's campaign highlighted her voting record aligned with Trump's priorities during his administration.
Republican strategists point to Hageman's electoral success as proof of her appeal within the party. She won nearly 70% of the vote in her 2022 House race against Cheney, a margin that demonstrated strong conservative support in the district. "Wyoming voters made their choice clear," said one Republican Party official. "They want representatives who will advance Trump's agenda."
Defenders of Hageman's campaign argue she represents mainstream Wyoming conservatism and criticize what they describe as media fascination with her primary victory over Cheney rather than policy substance.
What the Numbers Show
Wyoming ranks first among U.S. states in percentage of registered Republicans, making it reliably conservative territory for general elections. The Cook Political Report rates the at-large Senate seat R+23, the strongest Republican rating of any Senate race in the 2026 election cycle.
Hageman's 2022 primary victory over Cheney was decisive: she won approximately 66% of the vote to Cheney's roughly 29%, with other candidates splitting the remainder. The seat has been held by Republicans continuously for decades, and all statewide elected offices remain in Republican hands.
The Senate contest is part of an unusually large political turnover in Wyoming. For the first time in 32 years, the state has open races for governor, U.S. Senate and U.S. House simultaneously, creating a rare moment of transition in state leadership.
The Bottom Line
Hageman's nomination sets up a straightforward path to the general election in one of America's most Republican states. With Trump endorsing her candidacy and holding strong name recognition from defeating Cheney, she enters the race as the overwhelming favorite against whatever Democratic nominee emerges.
The November matchup will test whether Wyoming's deep red voter registration translates into another lopsided victory for the GOP ticket. Political observers see little chance of a Democratic flip in a state that hasn't elected a Democrat to federal office in recent memory. Hageman is expected to formally launch her general election campaign in the coming weeks, focusing on issues including energy policy and federal land management that resonate with Wyoming voters.
