It's not the position, it's the disrespect

Lots of liberals and bloggers have been railing against Joe Lieberman for regularly voting with the Republicans in the Senate and providing the cover of "bipartisan support" for legislation that the rest of the Democrats clearly oppose. He appears either to think he's immune from consequences or to be planning a move across the aisle.

Supporters say, why pick on Joe? There are other conservative Dems, many of whom have even more positions in common with the Republicans, and yet you pick on this nice guy from CT. Hmmm, I wonder why that could be? Perhaps because he keeps slamming his own leadership in public, and continues to be a public relations drag on a the attempts of Democrats to mount a meaningful Opposition... ?

Update: Another show of blatant symbolic disloyalty.
