The death of Sen. Lindsey Graham does more than leave a vacancy in the U.S. Senate. It also sets off an unusually fast political process in South Carolina, where state law requires both an interim appointment and an expedited election to determine who will appear on the November ballot.
Graham's death also comes as Republicans are already navigating uncertainty surrounding another longtime Senate fixture, Sen. Mitch McConnell of Kentucky. The 84-year-old former Senate Republican leader has been hospitalized since mid-June with undisclosed health issues and has not returned to Capitol Hill. While GOP leaders have said McConnell remains engaged in Senate business through phone calls, the lack of public information about his condition has fueled widespread speculation. McConnell, who announced last year that he will retire at the end of his term, is not seeking reelection in 2026, meaning Republicans are simultaneously preparing for two high-profile Senate transitions.
