I've known Hillary for 25 years, and when I was reading the first e-mail to her, the one about Bernie Sanders and whether he believed in God, I saw a look in her face that suggested she had never heard those words before. It was sort of look of "What happened? What are you talking about?" She's very good at being interviewed, and she said, "I don't know anything about this," and she wouldn't go into much depth, except to say that any reference to American politics is, on its face, the wrong thing to do. But I really had the sense she didn't know anything about it. You would be surprised by that, but here's my personal private theory: She was consumed all morning with Tim Kaine. They had to get to know each other. They don't know each other well. Then they walked into this 60 Minutes interview, and we completely surprised them.
