In an interview with CBS News Mitt Romney's wife Ann said it's the Obama campaign's strategy to "kill Romney."
“It makes you recognize that they are–gonna do everything they can– to destroy Mitt–so that he isn’t gonna be the person– that we have the confidence in, that I have the confidence in, to know that he’s the guy that can turn this economy around,” Ann Romney told CBS’ Jan Crawford. “They’re trying to portray him in a light that is just completely wrong…early on we heard what their strategy was. It was kill Romney… that was their memo that came out from the–from their campaign. And it’s, like, not when I’m next to him you better not." ...
“I feel like all he’s doing is saying, “Let’s kill this guy,” Mrs. Romney said, in the interview taped during their week-long vacation in Wolfeboro, NH.
ABC News notes Ann is referring to an anonymous Democratic strategist who was quoted in a news story last year as saying "Unless things change and Obama can run on accomplishments, he will have to kill Romney."
