Racial divide in Mississippi?

Okay, yesterday Obama won the Mississippi primary with 61% of the vote. The one thing that bugged me about the punditry was the notion that he only did so well because there are so many black people in Mississippi, getting 70% of the black vote. Here's the page on that from the exit poll. The idea is that he can't "reach across the racial divide."
Yeah, right. Here in Maine, which is whiter than Obama's teeth, he won the caucus 60/40. 'Nuff said? Here's another way of looking at it. Go back to that page, and see how the white lady did reaching across the racial divide. Clinton won 8% of the black vote. Obama won 26% of the white vote. Check my math, but that sounds like Senator Obama, yesterday, performed across the racial divide 325% better than Senator Clinton. And that's without going negative.
