Joe Lieberman is holding the entire Democratic Party hostage to his position on the war in Iraq. We cut funding for the war and he bolts and hands all the Senate committee chairs to the Republicans.

Sen. Joseph I. Lieberman of Connecticut told the Politico on Thursday that he has no immediate plans to switch parties but suggested that Democratic opposition to funding the war in Iraq might change his mind…

“I have no desire to change parties,” Lieberman said in a telephone interview. “If that ever happens, it is because I feel the majority of Democrats have gone in a direction that I don’t feel comfortable with.”

Asked whether that hasn’t already happened with Iraq, Lieberman said: “We will see how that plays out in the coming months,” specifically how the party approaches the issue of continued funding for the war.

He suggested, however, that the forthcoming showdown over new funding could be a deciding factor that would lure him to the Republican Party.

“I hope we don’t get to that point,” Lieberman said. “That’s about all I will say on it today. That would hurt.”

Chris Bowers also points to related problems.

So far, Lieberman is using his clout mostly in ways that discomfit his fellow Democrats, while his relationship with Republicans has involved more collaboration than coercion. When Senate majority leader Harry Reid said Bush’s State of the Union proposal for a bipartisan terrorism panel was redundant, Lieberman, who supported the idea, privately sent Reid a letter saying he was “upset.” Within days, Reid backed down and negotiated the panel’s makeup with the White House. And last month, after Lieberman told Reid he had stopped attending the weekly Democratic lunch because he didn’t feel comfortable discussing Iraq there, Reid offered to hold those discussions at another time. Lieberman has started attending again.

As Chris notes, this means the Democratic caucus cannot even discuss the most critical issue of the day because it makes Lieberman uncomfortable.

I think we should start working on flipping a Republican Senator. Does Olympia Snowe want a committee chair? How about Chuck Hagel? Anything is better than putting up with this blackmail from Lieberman.
