Among the first to arrive at Mar-a-Lago on Super Tuesday was Marjorie Taylor Greene, dressed in all black, at 4:30 p.m., when there were still just a handful of other people in the gilded ballroom. Within hours, of course, the royal court of Donald Trump had filled with red-hatted men and bleached blond women in sequins and leopard prints, who cheered as Trump pulled off a sweep (sans Vermont), essentially securing his coronation as the G.O.P.’s 2024 standard-bearer.

Over the din, Greene pitched me on why Trump ought to appoint her secretary of Homeland Security—and how she was ready to deport on day one. “My articles of impeachment were the ones that passed on the House floor, impeaching Secretary Mayorkas,” she reminded me. (Greene’s industriousness was somewhat undercut by the fact that she was one of only six members of Congress present; the rest of her colleagues were back in Washington, working to keep the government from shutting down.)
