Joe Lieberman is once again repaying Democrats for giving him the chairmanship of the Homeland Security Committee, going on Fox to argue that win or lose, Scott Brown's campaign demonstrates that Massachusetts voters are "unhappy" with Democrats in Washington, DC and that they were "really skeptical" of health care reform.
Watch:
Later in the interview, Lieberman refused to rule out Neil Cavuto's speculation that he might switch to the Republican Party if the GOP were to win control of the Senate next November, saying he had "no idea" if he'd make the jump.
By the way, this isn't the first time Lieberman has indicated his willingness to join the GOP. In December, he told CNN, "I don't know what I'll run as" in 2012. It was unlikely that he'd run as a Republican, he said, but "all options are open."
