Lead (white) Republican strategist/pundit says (black) Obama would have been pro-slavery

Calling a black man pro-slavery isn't just insane, it strikes me as overtly racist as well. The only reason Kristol is throwing this bizarre charge against Obama is because Obama is black. And I wonder whether Kristol is hoping that Obama reacts by saying something like "As a black man..." - i.e., give the majority-white public a quick dose of "remember, Obama is B-L-A-C-K."

And big surprise, the racist broadcast was on FOX.
