I felt he was on the defense way too much. He should have stuck to taking her down and asking the country if they are doing worse today than 8 years ago.
I really think something happened behind the scenes. I study him closely, and he never comes out already pissed - unless someone is fired that day.
He HATES liars - but he knew Hillary would be lying. He walked out already angry and it took him nearly an hour to get it controlled.
Something set him off - or set him up.
