Republican U.S. Rep. Harriet Hageman won the Wyoming GOP primary for the U.S. Senate seat on Aug. 18, advancing to the general election in November. Hageman defeated four primary opponents in a landslide, including National Guard veteran Jimmy Skovgard, rancher Sam Mead, massage therapist Jill Edwards, and John Holtz. The Associated Press called the race at 10:52 p.m. ET.
On the Democratic side, state Rep. James Byrd won his party’s nomination in a landslide over Billy Benavidez, setting up a general election contest in the state’s deep-red political landscape. The Associated Press called the Democratic primary race at 10:53 p.m. ET.
Hageman will face Byrd in the general election to succeed Republican Sen. Cynthia Lummis, who announced in December 2025 that she would not seek re-election after one term. Wyoming has not elected a Democratic senator since 1962, and political analysts widely expect Republicans to retain the seat.
Campaign Themes and Endorsements
Hageman, a fourth-generation Wyomingite and former lawyer, ran on a platform emphasizing government spending cuts, election integrity, opposition to surveillance, anti-abortion policies, and energy sector support. She secured the endorsement of former President Donald Trump, who called her a “TOTAL WINNER” in a Truth Social post on Aug. 4. Trump had previously endorsed Hageman in her 2022 campaign to unseat Rep. Liz Cheney, a prominent Trump critic.
Byrd, a former exploration geophysicist and IT project manager, campaigned on lowering rural healthcare costs, supporting energy jobs, and protecting public lands. He criticized Trump’s tariffs, arguing they had harmed Wyoming’s agricultural sector by reducing access to foreign markets. Byrd also adopted a more moderate stance on immigration, supporting stronger border security while opposing family separation policies.
Political Context and State Dynamics
Wyoming is one of the most Republican states in the nation, with Trump winning 72.3% of the vote in the 2024 presidential election. The state’s at-large House seat is also open after Hageman’s decision to run for Senate, with Republican Secretary of State Chuck Gray emerging as the heavy favorite to replace her in the House. The governor’s race is also open in this election cycle, marking the first time in over three decades that Wyoming has had open races for governor, Senate, and House simultaneously.
The Cook Political Report ranks the Senate race as solidly Republican (R+23), reflecting the state’s partisan lean. Hageman’s victory in the primary solidifies her position as the frontrunner in the general election, though Byrd will attempt to present a Wyoming-first platform to appeal to independent and moderate voters in a traditionally conservative electorate.
