Background

Sen. Cynthia Lummis of Wyoming, first elected in 2020, announced in December 2025 that she would not seek reelection, citing "difficult, exhausting session weeks."[2] Days later, Rep. Harriet Hageman, the state's lone member of the US House, entered the race.[4] Hageman, who had previously defeated Rep. Liz Cheney, won the Republican nomination in the August 18 primary.[4][3] In late September, her Democratic opponent, James Byrd, challenged her to a debate at a town hall in Casper.[5]
