Newt Gingrich’s “people-powered campaign” may be grinding to a halt. Sheldon Adelson, the third richest man in America and Newt’s main backer, has decided that $11 million is the limit and he’s not giving any more money. Could this finally be the stake through the heart of Newt’s zombie campaign? I think it was entirely unintentional from the start. I don’t think he ever thought he had a prayer of winning and his surge(s) surprised no one more than himself.
