I think one of the great explanations for the mess the Obama administration is in — the whole cowbell dynamic — is that he, his advisers, and many of his fans in the press cannot fully grasp or appreciate the fact that he is not as charming to everyone else as he is to them (or himself). Hence, they think that the more he talks, the more persuasive he will be. Every president faces a similar problem which is why, until Obama, every White House tried to economize the deployment of the president's political capital. The Obama White House strategy is almost the rhetorical version of its Keynesianism, the more you spend, the bigger the payoff.
I got nothin' to add. Just bow in the presence of the master.
