Rush has said many times that he would ‘vote for any one of these guys’ over Hillary Clinton. No, not an endorsement - but I think his acceptance of Trump as a candidate is meaningful...especially while the party leadership is plotting third party games.
I was telling someone else that I thought he was somewhat gracious at times, and then he would almost seem sorry and try to make up for it by being hard on him.
I saw others that seemed to think he was pretty hard on him too.
