Yes, that is what an uneducated white women asked during a campaign stop where McCain was. Obviously, he isnt an Arab, and if you know anything about him, or even read just a little, you would know that.
McCain did the right thing, in terms of explaining it, although don't go too far. After all, Obama is still a Democrat, and things like Ayers, Acorn, Rezko, and Wright are what kind of attitude you will get.
