Another Senate Republican quits as GOP grapples with Trump's tanking popularity

Sen. Cynthia Lummis (R-WY) became the latest Senate Republican to announce her retirement.

In a statement on Friday, Lummis said she would not seek reelection.

"It's an incredible honor to represent Wyoming in the U.S. Senate, and throughout my time here, Wyoming has been my one-and-only priority," she explained. "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."

"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," she added. "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."

Lummis's statement follows the announcements that Republican Sens. Mitch McConnell (KY), Joni Ernst (IA), Thom Tillis (NC), Marsha Blackburn (TN), and Tommy Tuberville (AL) would also not run for the Senate again.
