You’re absolutely correct that nobody is voting for Gingrich here. They’re voting for the deeply cherished fantasy that he will do to Obama what he’s done to Mittens.

Nothing else counts. When he scolds John King and Juan Williams, they can actually see him doing that to Obama. It doesn’t matter what he says. Nobody is listening to the words. They’re listening to that visceral, piggy-eyed hatred, and they love it. Romney’s mealy-mumbly management-speak imitation of the same performance exasperates them almost beyond endurance.

Guardian comment from ‘Natasha Fatale’

This is the most brilliant deduction I’ve read for why Gingrich is winning.
