What do you mean with respect to election outcome? McCain wins? McCain wins big? McCain loses close one?
If McCain wins, there is no question but that it will be blamed on racism. That is a given. Not only that, but it will be the racists who "stole" the election outright.
The main focus will be on the "despondency, despair and disappointment" of all African-Americans and the loss of hope that America will ever be anything but a racist country. There are going to be a bunch of pissed off people if Zero loses this election after being told all this time it was a lock.
