Watching Sarah Palin responding to Charlie Gibson's questions I was reminded of a student who was in way over her head. She really didn't understand the material but was working hard to mask her ignorance with some terms that she had gleaned from classmates. What she revealed in ignorance, she compensated for with earnestness and eye contact.
