Wyoming politics does not usually come with suspense, and this Senate race is shaping up to be no exception. Rep. Harriet Hageman officially jumped into the race Tuesday to succeed retiring Sen. Cynthia Lummis, and the move immediately locked in the direction this contest is headed. Another solid Trump ally is aiming for the upper chamber, and in a state like Wyoming, that matters.
Hageman’s announcement came just four days after Lummis revealed she would not seek a second six year term. That decision opened a rare Senate seat in one of the most reliably Republican states in the country. Trump carried Wyoming by 46 points in his most recent White House victory, and Sen. Tom Barrasso cruised to re election by more than 50 points. The electorate here knows exactly what it wants, and Hageman is offering it without apology.
In her launch statement and video, Hageman leaned fully into the America First message. She praised President Trump for making it acceptable again to say “Make America Great Again” and said it would be an honor to continue advancing that agenda in the Senate, just as she has done in the House. There was no hedging, no consultant approved vagueness, just a clear signal to voters about where she stands.

Hageman is best known nationally for one thing, taking out Liz Cheney. In 2022, with Trump’s backing, she ousted then Rep. Liz Cheney in the Republican primary. Cheney had become a prime Trump target after voting to impeach him following January 6 and later joining the Democrat led committee investigating the Capitol riot. Wyoming voters delivered their verdict decisively. Hageman went on to win nearly 70 percent of the general election vote and was re elected in another landslide in 2022, again with Trump’s support.
A Trump endorsement in this Senate race would surprise absolutely no one. Hageman has been a consistent ally, not a fair weather friend, and that loyalty tends to count in Republican primaries.
To her credit, Hageman praised Lummis as she launched her campaign, calling her service “principled, conservative leadership” and pledging to bring honor to the office if elected. Lummis cited exhaustion after this fall’s brutal government shutdown as her reason for stepping aside, a refreshingly honest explanation in modern politics.
A fourth generation Wyomingite and a leader in the Western Caucus, Hageman has built her brand around property rights, water rights, energy, and natural resource development. She has made it clear she intends to defend Wyoming’s ability to manage its own resources and remain a leader in energy and food production.
She is the first major Republican to formally enter the race, though Gov. Mark Gordon is rumored to be considering a run. Even if others jump in, Hageman starts with name recognition, a proven base, and alignment with the most popular political figure in the state.
In Wyoming, that is a powerful combination.
