Why would his being black be a factor at all?
I think his point was the unecessary charges of racism. If you disagree with communism, gun grabbing, the welfare state, etc., it has to be racism, and only racism, because how could anyone disagree with his policies?
If you disagree with his using other people children as a political shield - you're racist. They've already started calling it that. The only reasion you object to him using the kids is racism. There could be no other explaination - according to the left.
I’ve seen him on television looking 99% white, then the next time looking 99% black. I think he wears black face most of the time. Gets him subliminal guilt factor points...the compassionate negro.
