It’s important to remember that this same man told a Fox News Sunday audience five weeks ago that the Republican Party was “wonderful” and that he was “very proud” of it. Charlie Crist sings a much different song for David Gregory on NBC’s Meet the Press today. When Gregory asks Crist with which party Crist will choose to caucus, Crist tries to dodge it, saying he’ll “caucus with the people of Florida,” a nonsensical response that Gregory won’t allow to pass. Eventually, Crist declares that he could vote for a Democratic Majority Leader in the upper chamber as easily as a Republican:

GREGORY: “Would you vote for a Republican or a Democratic Majority Leader?”

CRIST: “I might not vote for either one. I’m going to vote for who I think would be best for the people of Florida. And if that happens to be a Democrat, so be it. If it happens to be a Republican, so be it. But I’ve got to look out for the people of my state.”

Oh, my. Joe Lieberman didn’t go that far when running as an independent. Everyone knew that Lieberman would caucus with the Democrats; the bigger question was whether the Senate Democrats would allow him to do so.

Many have questioned Crist’s sense in abandoning his party for a one-shot run at the US Senate, and this will only deepen the conviction that Crist has completely taken leave of his senses. Does he really believe that in 2010 the electorate wants to endorse current Democratic leadership in Congress? How many independents does he think he’ll win by assuring them that he’ll vote to maintain the status quo if he goes to Washington?

Crist has become a Party of One, trying to join a Caucus of One. That’s likely to be a great description of the rest of his political career.
