I’m real sure the tone of her questions on religion was disdainful.
She was bad, no doubt, but she often comes across that way, it really is her MO. She did that with lots of her questions, she also continued that way after the debate, but notably only with Trump and the women thing, not about religion.
After sleeping on it, it’s true she was extra snarky only about a few things, one of which was her disdainfully condescending question about God speaking to the candidates. I think it showed her in a poor light. It also demonstrated an unfortunate fact in America, that the past decade has become a time where Christians can be belittled openly without much push back from the public. The atheist left has made huge inroads and won a lot in the public square, meaning the media, Entertainment and in the schools.
Upon reflection Cruz did okay, was unapologetic, but should have gone all Newt on her. He should have taken on her question and attacked it as the gotcha it was, saying she was out of bounds, and shaming her for the condescension she demonstrated. He took the bait, when he should have gone on offense talking about the anti Christian bigotry she demonstrated.
It may have been his only error.
