That is not true. Newt gave an interview today, after addressing a Hispanic leadership event in Los Angeles, with the press today where he said straight up that most of his woes in polls and losing contests was directly related to him being off message. He explained that all the time going after Romney was damaging. That is why he is restating again that he is going to focus on policy.
I heard a political strategist on Fox one night saying that when an attack ad comes out against a candidate, the best way to handle it is to address it briefly and get right back on message. Ronald Reagan did that well. They said the last thing you should do is just not answer it like what happened to Newt in Iowa. Of course, on the other hand, the way the superpac attacked Romney did not serve Newt well either. What happened here in Florida with all the Romney attack ads was a disgrace. It is not easy to answer 19 million dollars worth of attack ads coming at you like napalm.
