I think his remarks emphasize the problem with using racist or racism and exemplify the attitudes of many whites who think they are liberal and open minded. Half the time they don't realize that what they are saying is based on stereotypes. Out of ignorance they say things that are hurtful and just plain wrong.

When reading other comments by Biden, I would guess that he falls into that category. He actually thinks he can make an issue of Black and/or white to advance himself politically. What he doesn't realize is that his remarks are devisive. Someone that stupid should never be president but if you consider the current president, it shows that maybe thats the kind of guy America wants. He's playing to the crowd.

Obama is intelligent and articulate. That probably a sure sign that he won't become president and that has nothing to do with his skin colour, it has more to do with the American public who perceive intelligence as a threat.
