Dems getting ready to play hard ball with Lieberman?

The Hill reports that some Democrats are actually beginning to understand the potentially dire political consequences of Lieberman's ego:

Democrats are worried that Lieberman may be giving Republicans a golden opportunity to undermine their message.

“I think there’s a lot of concern,” said a senior Democratic aide who has discussed the subject with colleagues. “I think the first step is if the Lieberman thing turns into a side show and hurts our message and ability to take back the Senate, and the White House and the [National Republican Senatorial Committee] manipulate him, there are going to be a lot of unhappy people in our caucus.”

Side show....that's exactly what Lieberman has become. Side show Joe. But his side show is undermining the Democratic messaging. He's putting his self-interest before the interests of the Democratic Party -- and Rove is playing him for the fool that he is.

Joe needs to know that there are consequences for his bad behavior.
