Personally, I think there's something disingenuous going on there. Of course a public plan has problems that have to be worked out in the legislation. But he was hired to work out those problems. And with 70% of the people wanting a "public option", i.e., government-managed health care rather than insurance company-managed health care, we don't want him talking about the other options that he and his corporate sponsors appear to be so fond of. We want him to address the problems with the public option and get it done.
Yes, he's a very smart man. He "talks policy" very well. He can sound very diplomatic, balanced, and informed while screwing you. I'm not saying that's what he's doing even though a large portion of his contributions come from corporations that are adamantly opposed to what the public wants. But I smell something unappetizing in his words, and I want his assurance that he'll do his job by doing what The People want him to do.
