Ten candidates are running in the Republican primary for the special U.S. Senate election in Oklahoma on June 28, 2022. The special election will fill the rest of the six-year term left by Sen. Jim Inhofe (R), who was last elected in 2020. Inhofe announced in February 2022 that he would resign on January 3, 2023, to spend time with family.
If no candidate wins more than 50% of the vote, a runoff featuring the two top finishers will take place on August 23, 2022.
Markwayne Mullin, T.W. Shannon, Nathan Dahm, Scott Pruitt, and Luke Holland have led in polling, noteworthy endorsements, and media attention.
