Markwayne Mullin and T.W. Shannon advanced to an August 23, 2022, Republican primary runoff in the special U.S. Senate election in Oklahoma. Neither received the majority of the primary vote needed to win outright on June 28.
Ten candidates ran in the primary. 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 he would resign January 3, 2023, to spend time with family.
Mullin, Shannon, Nathan Dahm, Scott Pruitt, and Luke Holland led in polling, noteworthy endorsements, and media attention.
