Time out: Ann Romney’s had enough. Responding to complaints about Mitt’s campaign in an interview with Radio Iowa on Thursday, Mrs. Romney challenged her fellow Republicans to take on the job themselves if they think they can do better. “This is hard. You want to try it? Get in the ring,” she said, urging them to realize “how lucky we are to have someone with Mitt’s qualifications and experience and know-how” as a presidential candidate. Romney seemed to shrug off criticism of his 47 percent comment and other recent jabs at his campaign, but Ann’s remarks suggest she and her husband are more concerned about the Republicans who have since distanced themselves from Mitt.
