Obama can't do this without support. Lieberman is the political version of old money in the Democratic party.Hopefully, you correct in your assessment. I'm looking at the splits in that poll, Warnock is only getting 39% of the black vote while the rest is split amongst the other candidates and undecideds. Lieberman is currently getting 17% of the black vote.
It's situations like this where I wish Obama would take a more active "boss" role in the party and lean on Lieberman to drop out.
People put their friendships over the country at the end of the day.
These older dems need to fix up.
