He’s apparently openly threatening to caucus with the GOP if he loses his committees. Knock yourself out, Joe. The Dem margin is big enough that we don’t need you, and you need a fucking spanking like nobody I’ve ever seen.

Josh Marshall puts it pretty clearly:

I think much of what Lieberman did over the last year was inexcusable. But magnanimity in victory is always a virtue and usually wise. So I don’t think it’s necessary to expel him from the caucus. And perhaps there are some perks of seniority he could be allowed to retain. But allowing him to keep his chairmanship is simply unacceptable. It’s a position the Democrats hold because of the joint efforts of Democrats across the country pulling together to support Democratic policies and ideals and elect Democratic candidates. For Lieberman to enjoy the fruits of that labor after working so hard to stymie that effort would be unconscionable.

Sen. Reid, show your mettle. Kick Joe to the curb. Connecticut will elect another Dem in 4 years, and even if they don’t, you’ll still have the majority.
