Mitt Romneys campaign must be upset with themselves.
Gingrich surged in December when Romney played nice, hoping to win on his record. But, like a conman, Gingrich is able to get people to look past the obvious red flags and pledge support. Gingrich, then, stopped playing offense and attempted to play the role of frontrunner and "mr nice, presidential guy". Meanwhile, Romney hammered him in Iowa with negative, and true, ads, and Gingrich went from a 15% lead to finishing in a distant 4th place in 3 weeks. Then he got creamed in NH. Romneys campaign left him for dead, and stopped attacking. In the pause between attacks, Newt reimmerged and won SC. Now, Romney is attacking again, and Newt is once again hitting the breaks on him emotion, and containing himself. It will be interesting to see if history repeats itself.
Its like on one hand, everybody knows Romney is the smarter guy, and has the better record. But, he has no emotion. When he shows emotion, you see the support flooding to his way.
On the other hand, its like with Newt, he comes off as having all the traits people with Romney had, and when Romney tries to play frontrunner and layoff the attacks, people flock to Newt emotion.
The gop just seems to LIKE the attacker; acting "Presidential" and being above the fray has proved to be a bad thing thus far. I think if Romney continues the attack, regardless of what Newt does, Romney will win. The way support flows his way when he calls Newt speaks for itself. People want to like Romney, Newts win is their way of telling him to show more emotion.
