Herb Cain doesn't know what the hell he is talking about. Perry couldn't have painted over the rock had he wanted to since he didn't even own the property. Cain would have been better off acknowledging he needed more information about this before sliming Perry with the race card. This is basically the same thing as Barry Obama's "Cambridge Police acted stupidly" comment. The only reason it is being defended on FR is because of a handful of anti-Perry posters, and Herb Cain's own ignorance about it before opening his yap.
I also like how Herb is allowed to apologize for this, but Perry isn't allowed to apologize for his "you don't have a heart" gaffe, but that's for another time and place.
