Two underdog candidates advanced to a runoff election in Oklahoma’s 2026 Democratic Senate primary after no candidate clinched a majority of the vote.
N’kiyla Jasmine Thomas, a nurse and Chickasaw Nation citizen, and Jim Priest, a lawyer and ordained minister, will compete in an Aug. 25 runoff election, according to The Associated Press.
Thomas won 45% of the vote, followed by Priest, who registered just under 24% support.
The winner will face Rep. Kevin Hern, R-Okla., who easily clinched the GOP nomination for the deep-red Senate seat and avoided a runoff election. Hern is endorsed by President Donald Trump and Senate Majority Leader John Thune, R-S.D.

6 MONTHS TO MIDTERMS: THE SENATE SEATS THAT COULD TIP THE BALANCE OF POWER
Under Oklahoma law, if no candidate secures more than 50% of the primary vote, the top two vote-getters will compete in a runoff election.
Sen. Alan Armstrong, R-Okla., a former energy executive who currently represents the seat, was barred by state law from seeking election for a full Senate term. He was appointed by Gov. Kevin Stitt, R-Okla., to replace Department of Homeland Security Secretary Markwayne Mullin in March.
The Democratic primary winner will face an uphill battle in the ruby-red state that voted for Trump by a 2-to-1 margin in 2024. A Democratic candidate has not won a Senate race in the Sooner State in more than 35 years.
National Democrats have not invested in the race, signaling little expectation it could flip.

Priest mounted a failed bid for Oklahoma attorney general in 2010 but was soundly defeated by 20 points. He previously led two nonprofits, Goodwill Industries of Central Oklahoma and Sunbeam Family Services, according to the Oklahoma-based outlet NonDoc.
Hern has vastly outraised Democrats, with a $6.8 million war chest, according to recent Federal Election Commission filings. Priest entered June with $117,000 cash on hand, while Thomas had just over $546.
The two leading Democratic contenders also have a minimal online presence.
An X account associated with Priest’s campaign had just 20 followers as of Tuesday. Meanwhile, a campaign X account affiliated with Thomas had just over 160 followers.
