Wyoming Sen. Cynthia Lummis is retiring from the Senate after a single term, leaving behind an open seat in a reliably red state.
She’s the fifth Republican senator to decide against running for reelection to the chamber in 2026.
Lummis, 71, a strong ally of the crypto industry, said the decision represented “a change of heart.” In March, she had earned an endorsement from President Donald Trump for her reelection campaign.
