I haven’t followed Tucker closely, but he seems to have gone cuckoo.
It happened to Glenn Beck.
Some people cannot handle fame or popularity.
Rush seemed to handle the spotlight, but seemed to phone it in towards the end. That is typical for everyone in life. The excitement or interest fades in their iob and life.
It may be that some people cannot handle fame or popularity, and it may also be that they simply connot face evil (and some cannot even acknowledge the existance of evil) and accept that evil must be destroyed. Among decent people, this is an understandable, although not a moral position to take.
Rush had a pronounced dislike for conspiracy nuttism. He said that he once got duped by some crackpot group while in Kansas City and the experience made him very careful afterwards.
Beck, and now Tucker, haven’t got the same finely tuned bulls#it detector that Rush had developed.
