I have read a lot of debate commentary, some pro and mostly con. Seemingly a majority of the commentariat was disappointed in both candidates, with the preponderance of their disappointment falling on the guy they didn't support before it started.
One of the more interesting ideas I read was that Trump was establishing himself as the alpha male in the room, which of course he did. That tends to be attractive to many male voters, and some women as well.
The management of Fox News said nice things about Chris Wallace's performance as moderator. If sincere, they were the only ones who thought so. Everyone else on both sides thought he failed, big time.
I see the Fox News heads as feeling the need to defend their Sunday show host, and their own failed judgment in employing him. Wallace is as bad a mismatch at Fox as Billy Graham would have been going on the hadj.
What we all got to see was two candidates for the nation's (and maybe the world's) toughest job functioning under stressful conditions. That isn't an altogether bad thing to watch, there is much to be learned.
