The idiots who keep re-electing this moron. To them, she's a demi-god, and anyone who doubts is a raciss'.
Then obviously they do not "do" any intellectual processing. They just automatically pull the lever for this idiot. So they are just as stupid as she is. Probably their highest intellectual achievement has been to utter the word "Duh". When she dies, they will find some other vicious racist who says the right things ("You are not responsible for your own poverty, the white man is") and elect them until they die, etc.
