Obama is not a good actor and perhaps this is what is disconcerting about him. He is playing a role, playing at running for President, dressed for the part, knows his lines, understands the technique, but can’t quite deliver…because it’s an act. He’s thin. It’s all talk. Does anyone know what his convictions are? I think he does, but he will not say because he knows they would be unacceptable in a President of the United States of America.

I don’t know about twitching, but lecturing, interrupting and glaring, yes.
