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

Lieberman, a registered independent who caucuses with Democrats, has been among the strongest supporters of the war and President Bush’s plan to send another 21,500 combat troops into Iraq to help quell the violence there.

"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."

He's never gone this far in his comments before, and one suspects that it is only a matter of time, especially if Democrats mount a serious effort to impose disabling restrictions on the president's conduct of the war, before Lieberman could very well formally cross the political aisle.
