After Rick Perry "sucked the oxygen out of the room,” Michele Bachmann is hoping to breathe some life back into her campaign: Her veteran campaign manager, Ed Rollins, stepped aside on Monday as did his deputy David Polyansky. Rollins will remain in an advisory role while Polyansky is leaving altogether. “I’m worn out,” Rollins told Politico. He’ll be replaced by Keith Nahigian. Meanwhile, the latest Rasmussen poll of Iowa showed Perry surging past Bachmann to a 29–18 lead.
