About this race
The 2026 United States Senate election in Oklahoma will be held on November 3, 2026, to elect a member of the U.S. Senate to represent the state of Oklahoma. Congressman Kevin Hern is the Republican nominee. The Democratic nominee will be decided in a runoff on August 25 between attorney Jim Priest and nurse Jasmine Thomas after no candidate received a majority of the vote in the June 16 primary. Republican appointee Alan S. Armstrong, who was named to the seat in March after Markwayne Mullin resigned to become secretary of homeland security, is prohibited from seeking a full term. Democrats have not won a Senate election in Oklahoma since 1990.
Despite the resignation of Markwayne Mullin, this is not a special election. Oklahoma is one of two states, along with South Carolina, that had vacancies in Senate elections already regularly scheduled for 2026.
