The actual content of what he says isn't even relevant anymore. Joe Lieberman's descent into self-parody centers on one thing: his rejection by Democratic voters in 2004 and 2006. We didn't vote for him, and for as long as he can claw his way into the spotlight, he's going to use it to say whatever he thinks might hurt us.
In the face of the massive buyer's remorse Connecticut's voters are feeling over him, Lieberman had to go an extra-special step too far:
NAPITALIANO: Hey Sen. Lieberman, you know Barack Obama, is he a Marxist as Bill Kristol says might be the case in today’s New York Times? Is he an elitist like your colleague Hillary Clinton says he is?
LIEBERMAN: Well, you know, I must say that’s a good question. I know him now for a little more than three years since he came into the Senate and he’s obviously very smart and he’s a good guy. I will tell ya that during this campaign, I’ve learned some things about him, about the kind of environment from which he came ideologically. And I wouldn’t...I’d hesitate to say he’s a Marxist, but he’s got some positions that are far to the left of me and I think mainstream America.
See that last bit? Joe wants to link his own opinions and those of "mainstream America." So to do it, he tries to take down a guy for whom mainstream America has shown far more fondness than it ever did for him. That's the only kind of relevance he's even trying to have these days. It would be sad, if anyone gave a damn anymore about what happened to Joe Lieberman.
