CNN reporting today that South Carolina blacks are split on who to support and that’s making a difference in a larger poll of Dems. As I’ve said before, the bad thing about being on top by a ridiculous margin is that the numbers have nowhere to go but down. But when Terry McAuliffe was in town a few months back, he told us they were running like it was a close race. And here we are.

I have a feeling it will come down to electability. Clinton leads on that measure. Whether that changes has nothing to do with Hillary at this point. I think most Democratic voters consider her electable. It’s up to Obama to show undecideds that he can take on the Republicans. If not, they’ll head for Clinton at the polls.
