So I post this most cogent and brief piece from Lawyers, Guns and Money:
I will concede that at the time the decision was made, we didn't know whether the decision to let Joe Lieberman keep his chairmanship was a good idea or not. Well, at this point we know it was a disaster, and surely relieving him of his perks has become a no-brainer. This isn't a question of balancing a desire for revenge against the pragmatic interests of the party. Continuing to reward people who double-cross you and continuing to trust people who have proven beyond a shadow of a doubt that they can't be trusted is just bad strategy.
