Former Senate majority leader Trent Lott (R-Miss.), now a D.C. lobbyist, warned that a robust bloc of rabble-rousers spells further Senate dysfunction. "We don't need a lot of Jim DeMint disciples," Lott said in an interview. "As soon as they get here, we need to co-opt them." But Lott said he's not expecting a tea-party sweep. "I still have faith in the visceral judgment of the American people," he said.
