I have to respectfully disagree with you. Honestly, where I live in middle, small town USA, there is no outrage over this story (if people even have heart of this) This seems like a big deal to people who watch the news and the candidates.

A lot of people want change and will continue to go over to the Democrats side- especially if the economy keeps going in what feels like a downward spiral.
This won't stop them. A speedbump in the road maybe, but not a road block.

He may get the nomination, but his chances of winning the general are zero.

And after being exposed to this level of black hatred (possibly for the first time), their votes are going to McCain. It could be a blowout of Reagan/Carter proportions.
