Congresswoman Who Defeated Liz Cheney Launches Senate Bid

Rep. Harriet Hageman (R-WY) is running to succeed outgoing Republican Sen. Cynthia Lummis in the United States Senate.

“We must keep up this fight, and that’s why today, I’m announcing my campaign for United States Senate,” the Republican said in a campaign video on Tuesday, which featured her 102-year-old mother, Marion Hageman.

“This fight is about making sure the next century sees the advancements of the last, while protecting our culture and our way of life,” she added.

Hageman gained nationwide attention in 2022 for defeating former Rep. Liz Cheney in the Republican primary after an endorsement from President Donald Trump. Hageman blew past Cheney with 66% of the vote to Cheney’s 29%. Cheney, formerly the chair of the House Republican Conference, became a staunch opponent of Trump and campaigned with Vice President Kamala Harris in the 2024 election.

Wyoming has a singular at-large House district, and Trump campaigned for Hageman in May 2022 in Casper.

“I spoke with Harriet yesterday— She will be one of the best US Senators in the country. No question. We need her in there!” Tyler Bowyer, COO of Turning Point Action, posted to X on Tuesday. It’s unclear if any other major candidates will enter the Republican field at this point.

The seat is considered to be solidly Republican, according to the Cook Political Report. Lummis won in 2020 with nearly 73% of the vote, and Trump won the state in 2024 with nearly 72% of the vote. Wyoming has a population of under 600,000 people.

As for Lummis, she announced that she would not be seeking a second term in the upper chamber on Friday. The senator was known as a leader on cryptocurrency policy as well as energy.

“Deciding not to run for reelection does represent a change of heart for me, but in the difficult, exhausting session weeks this fall I’ve come to accept that I do not have six more years in me. I am a devout legislator, but I feel like a sprinter in a marathon. The energy required doesn’t match up,” Lummis, 71, stated.

“I am honored to have earned the support of President Trump and to have the opportunity to work side by side with him to fight for the people of Wyoming. I look forward to continuing this partnership and throwing all my energy into bringing important legislation to his desk in 2026 and into retaining commonsense Republican control of the U.S. Senate. Thank you, Wyoming!” she continued.

If elected, Hageman would be serving alongside Senate Majority Whip John Barrasso, who was re-elected in 2024.
