I thought he was great on that show today. I think he could actually be a decent replacement for Rush. He is smart and witty.
He has an astute ability to clean up his language compared to his various interviews and podcast appearances. ;-)
AS a trial lawyer he is REALLY good at presenting his points - with citations. And then burns opponents with sarcasm and ridicule.
Personally I like his non-fiction as much as his fiction.
Clearly .45 is his favorite caliber.
