Chris Wallace is from Fox News. That is about as good as you can expect. I was actually expecting worse from the moderating considering Fox is so right wing. I was really surprised to watch Wallace challenge Trump on some of his positions. But yes, it was refreshing to watch Hillary Clinton make such a strong and well articulated stand. It is very rare in the United States to see such commitment from a political leader.
Chris Wallace may be on Fox, but he is a first-class anchor and interviewer. He is not in thrall to the extreme right wing. In fact, I believe he is a registered Democrat. If anyone deserves the ridiculous moniker "fair and balanced", it's him.
IMO, he was far and away the best moderator in the Presidential or Vice-Presidential debate cycle.
