It's good to be Joe Lieberman. He campaigned against Barack Obama, even speaking at the Republican convention, yet Barack Obama wanted to keep him in the Democratic caucus. He single-handedly weakened and tried to undermine the Senate health care bill, but gets thanked by the President. If he runs as a Republican, the Democrats will probably make him Majority Leader (assuming the Democrats still control the Senate in 2012.) And, Lieberman as the GOP candidate is a possibility:
Lieberman said he wasn't sure which party, if any, he would represent in his next election.
"I like being an independent, so that's definitely a possibility," the Connecticut senator said. "But I'd say all options are open."
He called running as a Republican "unlikely" but added that he wouldn't "foreclose any possibility."
