The GOP base:
In the Vanderbilt Poll, conservatives comprised a majority of every major candidate’s supporting coalition. However, only Cain and Gingrich drew more than 80% of their support from avowed conservatives. … It is hardly surprising that Cain’s supporting coalition looks so solidly conservative. But it is a big surprise in the case of Gingrich. Remember, this is the guy who was being excoriated just six months ago for denouncing the Republican budget as “right-wing social engineering.”
Chait wonders whether the Newt bubble will pop:
Gingrich has tons of liabilities — non-orthodox positions, erratic behavior, little money or organization — but he does have experience in the national spotlight. It's not completely inevitable that he will implode.
