Here's Newt's attack line
“You have to ask the question, is capitalism really about the ability of a handful of rich people to manipulate the lives of thousands of people and then walk off with the money?” [...]
Wow, that's kind of the heart of the matter, isn't it?
Romney is incredibly vulnerable in the general election in two ways. First, he is just not very likable. He's not genuine. I would even argue he has no integrity. Not in the sense of he's a liar and a cheat, but that he lacks the integrity that allows you to be genuine, to be who you are, to be the same person regardless of the situation and who you are talking to.
Second, Bain Capital is just the perfect example of the financialization of America's economy. This guy is the living embodiment of what #OWS was yelling about. And while #OWS eventually got smeared by the drum circles and the anarchists, the basic message found real resonance with Americans, because the average American looks at the last four years and sees a system that rewards the rich and punishes everyone else.
Maybe it's just that Newt knows better than anyone how to stick the knife in, but that last line about free markets versus predatory capitalism... Man, that's brilliant. Succinct and believable precisely because it comes from a Republican. Maybe Obama has more trouble leveling that line of attack because he's been attacked for four years as being a "Socialist," but if this becomes the narrative, Romney is doomed.
Calvin Coolidge, that most conservative of Presidents, said that, "A man who builds a factory builds a temple." What do we say about the man who shutters that factory and lays off the workers? What do we say about the money changer in the temple?
