Obama delivered a compelling, almost mesmerizing, speech, did not talk about any issue in detail and took no questions. His event lasted just over half an hour. Clinton talked about issue after issue in almost mind-numbing detail and answered question after question in an event that lasted more than an hour and a half. Both drew large crowds. But Clinton’s crowd was much smaller at the end of her speech than at the beginning. Hundreds of people trickled and then streamed out while Clinton was still talking. But she went on and on as if she did not mind. And maybe she didn’t. “You campaign in poetry, but you govern in prose,” Clinton said, quoting Mario Cuomo. In other words: Dull is good. Dull is a sign of competence.
