I'm assuming the same could be have been said for Newt if he had won. I've read that the level of negativity is wearing thin on voters, and we've still got "46 states to go" as Gingrich proclaims. IF this fight wears out over the long haul, I could see them running the risk of turning off lots of people, regardless of how positive they may want their overall message to be.
