You know, there was a time when Joe Lieberman actually had a reputation for being a person of singular integrity. Thankfully, he's outgrown that stage:

Mr. Lieberman had supported the Medicare buy-in proposal in the past — both as the Democrats’ vice presidential nominee in 2000 and in more recent discussions about the health care system. In an interview this year, he reiterated his support for the concept.

But in the interview, Mr. Lieberman said that he grew apprehensive when a formal proposal began to take shape. He said he worried that the program would lead to financial trouble and contribute to the instability of the existing Medicare program.

And he said he was particularly troubled by the overly enthusiastic reaction to the proposal by some liberals, including Representative Anthony Weiner, Democrat of New York, who champions a fully government-run health care system.

“Congressman Weiner made a comment that Medicare-buy in is better than a public option, it’s the beginning of a road to single-payer,” Mr. Lieberman said. “Jacob Hacker, who’s a Yale professor who is actually the man who created the public option, said, ‘This is a dream. This is better than a public option. This is a giant step.’”

Yes, this is a grown man, an elected member of the most august and exclusive club in the country, who if the people had had their way in 2000 would have spent eight years a heartbeat away from the Presidency, saying that he changed his mind on an important issue, one that will have definite life-and-death consequences in the real world, because a liberal congressman said he agreed with him (incidentally, the quote from "Prof. Hacker" is completely made-up). Is there no bottom to the man?
