If you have been accused of having "derangement syndrome" blame him. He was a member of the DSM III and coined the term in reference to opponents of Bush the younger. The concept is truer now than ever and applies to people all over the political spectrum.
He is loosely what would we would call a "neocon". He has been a fierce critic of Trump on many levels but is just as much opposed to a lot of what the resistance says and their tactics.
As mentioned in the video above his many of his hopes were dashed when he fractured his neck in a diving accident in college but reacted to his paralysis by being a prime example of "making the best of a bad situation". Despite seeing him on TV a good number of times I did not know he was paralyzed until reading about it in Wikipedia. I found the note to readers disclosing his dire situation a prime example of being classy while not being wishy-washy.
That a voice that does not toe to the resistance or Trumpian lines is going to be silent is just a continuation of a disturbing and destructive trend.
Below is from an appearance on the Tucker Carlson from August of last year discussing his opinions about the Muller investigation, Trump voters, and impeachment, topics still very relevant.
