Some Democrats feel like they're in a jam, Simmons said. If Clinton wins, the black vote might not turn out for her in the general election. If Obama wins, political ads featuring Wright will blanket the airwaves and Internet.

It seems to me that the worry over the black vote is, at least in part, driven by the Obama campaign's attempts to smear the Clintons as personally racist (the fairytale, MLK crap).  Sure, there were some unfortunate comments by Clinton surrogates, but it's Obama's repeated playing of the race card that is the real culprit here, IMO.  And I think Obama's statements about Hillary not getting his voters are designed to play onto those fears and essentially try to convince the SDs they have no choice but to vote for him.  Now, ordinarily, you might think the guy threatening to split the party wouldn't be rewarded, but I'm not so sure about that.

It's remarkable to me that a campaign that has so often leveraged Reps/Indys against democrats, used rightwing framing on healthcare, has worked to portray the last successful democratic president as a racist, and has essentially threatened to take his voters and go home if he doesn't get his way, is considered the party of Unity, while Hillary - who has repeatedly said the party would unite behind the nominee and run a partisan, democratic campaign - is alleged to be secretly plotting a McCain victory.
