He didn’t really call her a bitch, as much as he commented upon the question posed to McCain. It is probably better to keep these kind of comments behind the scenes, however it was a female who asked the question in the first place, and many women feel that way about Hillary.
Do we know the name of the woman who asked the bitch question?
True, but it's like the n-word. Chris Rock can use it to make people laugh, but I can't for practically any purpose. Rove needs to remember that only a woman may get away with using that word about another woman, or even refer to it, unless criticizing it.
