Rep. Harriet Hageman announced her candidacy for the U.S. Senate seat being vacated by Sen. Cynthia Lummis. A Cheyenne attorney and Wyoming’s sole U.S. representative, Hageman is best known for defeating Liz Cheney in the 2022 Republican primary and was re-elected to the House in 2024 with more than 70% of the vote. Hageman emphasizes protecting Wyoming’s energy and agricultural industries; Lummis said she will not seek re-election due to stamina concerns. Wyoming has not elected a Democrat to Congress since the late 1970s.

Rep. Harriet Hageman, Wyoming’s lone member of the U.S. House of Representatives, announced on Tuesday that she is running for the U.S. Senate seat being vacated by Sen. Cynthia Lummis.
A Cheyenne-based attorney known for representing ranchers, Hageman became a prominent national figure after defeating Rep. Liz Cheney in the 2022 Republican primary by more than a 2-to-1 margin. She then won the general election in heavily Republican Wyoming and was re-elected to the House in 2024 with over 70% of the vote.
In her campaign statement, Hageman emphasized Wyoming’s resource-driven economy and vowed to protect the state’s energy and agricultural leadership.
“I will always defend Wyoming’s ability to access, manage and use our natural resources to fuel our economy,” she said. “We must ensure that Wyoming remains a leader in energy and food production to help us maintain our way of life.”
Sen. Cynthia Lummis, who has served in the Senate since 2021 and previously held multiple statewide and federal offices, announced last week that she will not seek a second term. Lummis cited concerns about the physical demands and stamina required for another six-year term.
Wyoming remains a solidly Republican state: no Democrat has represented the state in either the U.S. House or Senate since the late 1970s. Hageman’s entry makes her the first major candidate to formally join the race following Lummis’s announcement; the seat is expected to draw attention in GOP circles as candidates prepare for the primary and general election cycles.
What This Means
Hageman’s candidacy signals an early consolidation of Republican interest around a candidate with strong support in the state’s conservative base. Her campaign message centers on energy, agriculture and natural-resource management—issues that strongly resonate with Wyoming voters.
