Former Democratic Rep. Kendra Horn, who won one of the biggest upsets of the 2018 election cycle only to lose two years later, said Tuesday she’s running for Senate in Oklahoma.

Horn is seeking the Senate seat that Republican Sen. Jim Inhofe will leave in January 2023 after holding it for 28 years. Horn, 45, won a stunning 2018 victory against GOP Rep. Steve Russell, becoming the first Democratic woman to represent Oklahoma in Congress. In 2020, with former President Donald Trump dominating in Oklahoma despite losing to Joe Biden, Horn came up short in her reelection bid against Republican Rep. Stephanie Bice in the 5th Congressional District, covering most of Oklahoma City.
