Beck didn’t set her up. Several people emailed him about her being a truther. That’s why he asked her.
Well, I guess that what “setting up” amounts to is a debatable point. What I’m saying is that even if he planned it ahead of time as something likely to trip her up, and even if his personal preference was for Perry, as some have said, more power to him. Reporters are allowed to ask probing questions. It was a legitimate question, and it prompted her to stumble and reveal herself for what she is.
