The health care summit is off to an already soporific start. How anybody will be able stay awake for the next six hours is beyond me. An early highlight: When they entered the room, both President Obama and Vice President Biden spent a few moments greeting the participants. Obama made his way to his seat efficiently. Biden, as you might imagine, did not. He kept chatting up his old friends in the Senate, and tried making some new ones from the House. But Obama grew impatient. "C'mon, Biden," he said from his seat. His tone was good natured, and everybody laughed. But you get the feeling that's something the president says often.
