Yep. When a black female U.N. ambassador lies to the American people, republicans pick on her, but only because of her race and sex. When a black occupant of our White House turns out to be an anti-American communist, we only pick on him because of his race. When a black Attorney General supports and condones lawless conduct ranging from Black Panther voter intimidation to Fast and Furious, the republicans only pick on him because he's black. That race card gets a whole lot of mileage!
Why Rice was sent out has been clarified. She was untouchable.
