Given the speed at which he talks, it's actually not that long a quote, but it's worth watching in full. The suddenly sane Chris Matthews dismantled the "single issue" argument in a discussion with half-hearted Lieberman supporter Don Imus this morning (YouTube - hat tip CTBlogger):

If you vote for Lieberman, he's not going to change his position. He's going to be for the war, and the first phone call he gets will be from Bush saying, "Congratulations, Joe, for hanging in there." And that's Lieberman's problem. He's gotten connected to this president....

Well [his support of the war is] not a mistake. It's not a youthful indiscretion. Look, he's further right than the president, probably....

This is one of the few times you actually can go to a voting booth and vote for or against the war.... I think everybody should vote and say "wait a minute. This is the rare chance I get to say whether we should have gone into Iraq or not. Whether we should have these policies."...

It's a very important time to vote on something that matters more than all the other things Joe talks about. Was he right or wrong about this war? Because he's going to be for that position again. If we attack Iran, tomorrow morning Joe will be out there saluting. First up - he'll be the first guy to salute in the morning. It's his future policy you're voting for....

IMUS: "You're certainly not helping things here, Chris..."

Lieberman yesterday:

"You know, I'm in a big fight here, and I understand that ... and as our mutual friend who's coming in later today, President Clinton, always reminds us, every campaign is about the future," he said.

Sen. Lieberman was right. And so was Matthews. Every campaign is about the future.
