Once Cruz allowed Glenn Beck into his campaign it was over.
Even when Beck was a big star on Fox News, there was something about him that didn’t seem emotionally stable. His positions on policy were great, but he sometimes went over the edge a bit too much. It got worse with time.
It was most noticeable when David Barton of Wall Builders was on. Barton would sometimes have that look of “I’m not sure I want to be associated with this guy.”
