WASHINGTON — U.S. Sen. Cynthia Lummis (R-Wyo.) announced she will not seek reelection in 2026, setting the stage for an open Senate race in one of the most reliably Republican states in the country.
Lummis said she will step down when her current term ends Jan. 3, 2027, closing out a single term in the Senate and ending her time as Wyoming’s senior senator.
Decision sets up open race
Lummis’ retirement creates a rare open-seat contest in Wyoming, where Republicans have dominated statewide federal elections for decades.
Her decision is expected to trigger a competitive Republican primary ahead of the state’s August 2026 primary election. The winner will advance to the November general election, where the GOP nominee is likely to be favored.
Several potential candidates are expected to consider the race, though no major contenders have formally announced.
First woman elected to Senate from Wyoming
Lummis was first elected to the Senate in 2020, succeeding longtime Sen. Mike Enzi. Her victory made her the first woman to serve as a U.S. senator from Wyoming.
Before joining the Senate, Lummis served in the U.S. House and held various state-level offices, building a long political career centered on conservative fiscal policy and energy issues important to Wyoming voters.
Impact on 2026 cycle
Wyoming’s seat will be one of several open Senate seats nationwide in the 2026 midterm election cycle. While the state remains solidly Republican, open seats often draw increased attention and spending during primaries.
Lummis’ exit gives Republicans the opportunity to nominate a new standard-bearer while offering Democrats a fresh, though uphill, chance to compete in the general election.
For now, the focus shifts to who will step forward to replace her and how crowded the Republican primary field may become.
