The American Prospect's Paul Waldman calls Romney's campaign trail laugh the "phoniest laugh in the world."
I'm sure that at times Romney laughs with genuine mirth, but you know the laugh I'm talking about. It's the one he delivers when he gets asked a question he doesn't want to answer, or is confronted with a demand to explain a flip-flop or a lie. It's the phoniest laugh in the world, the one New York Times reporter Ashley Parker wrote "sounds like someone stating the sounds of laughter, a staccato 'Ha. Ha. Ha.'" Everything Mitt Romney is as a candidate is distilled within that laugh—his insincerity, his ambition, his awkwardness, and above all his fear. When Mitt laughs that way, he is not amused. He is terrified. Because he knows that what he's saying is utter baloney, and he knows that we know it.
