Wyoming Rep. Liz Cheney, Donald Trump’s fiercest Republican adversary in Congress, was defeated in a GOP primary Tuesday, falling to a rival backed by the former president in a rout that reinforced his grip on the party’s base. The third-term congresswoman and her allies entered the day downbeat about her prospects, aware that Trump’s backing gave Harriet Hageman considerable lift in the state where he won by the largest margin during the 2020 campaign. Cheney was already looking ahead to a political future beyond Capitol Hill that could include a 2024 presidential run, potentially putting her on another collision course with Trump.
