It's an interesting dilemma. On the one hand, you have a point. You really would like for your candidate to be able to handle a question from an airhead reporter about what they read.
On the other hand, I remember people, mainly in the media, saying the exact same thing about Ronald Reagan, and he worked out pretty well. She has two things none of the other republican candidates possess: charisma and ordinary voters adore her. She may not be a Rhodes scholar, but she has bigger balls than all the other republicans put together.
