Well, you have to remember, back in 2006 he promised to get a democratic president elected. Especially galling for democrats is the nominee is the same guy who actively campaigned for him in the democratic primary.
Needless to say, as Joe stabbed the dems in the back for some perceived slight, he’ll stab the GOP in the back without a second thought.
Joe Lieberman doesn’t care about America, he only cares about Israel and himself (I’m not sure in what order), the GOP & McCain would be wise to keep him at arm’s length.
I have never advocated that Joe become a republican. I merely think that if the Dems have already dumped him he should remain an independent in fact as well as in name.
