"Racial" or "Racist"?

Instapundit dubs this Rasmussen poll a "racial split". Reynolds certainly points out the money quote: "But, among white voters, Clinton leads 41% to 27%. Among African-American voters, Obama leads 66% to 16%." Liberal pundits who suffer from white guilt, such as Chris Matthews, love to attack whites by claiming that whites vote against black candidates on the basis of race. Undoubtedly, some whites do that. Matthews would most assuredly call them racists. But what do you call it when blacks vote for someone because of his race? You don't have to be a statistical genius to see the disparity among whites and blacks in choosing their candidate, apparently based on race. Blacks overwhelmingly support the black candidate, to a much greater degree than whites support the white candidate. This was the same issue I pointed out earlier with respect to Harold Ford, Jr. I suppose one could argue that blacks believe that the black candidate is more likely to support "black issues" whatever that is. Isn't that a racist, stereotypical assumption in and of itself? Is Hillary's record on issues affecting blacks any worse than it is on issues affecting other races?
