how many Obama voters are racists?

A provocative question/observation from Chuck Muth:

I have a politically incorrect question to ask about race and the Barack Obama race.

It’s a certainty that a lot of white voters have been voting against Obama only because he’s black. And that, of course, is racism. But on the other hand, an awful lot of black voters - in the neighborhood of 90 percent - are voting FOR him, apparently only because he’s black.

Um, isn’t that racism, too?

I mean, when it’s a black Democrat vs. a white Republican, you can at least pretend that the black vote is going to the black candidate simply because of philosophical differences between the liberal Democrat candidate and the conservative Republican one. But when it’s a black liberal Democrat vs. a white liberal Democrat…and 90 percent of the black vote goes to the black candidate…you just can’t explain it any other way than…racism.
