Motley:  You're right.  Rush has his fans, whom he condescendingly calls "ditto-heads" who accept his every word as truth and cheer as he delivers his insults.  As you say, it's made him a multi-millionaire.  Often I wonder...is this guy for real? or has he found a great little niche market for hatred and is milking it?  He can't possibly believe what he says as, even though his thought process may be clouded by oxycontin, he is a bright man.  

However, I believe that he, much like Trump, is amoral and really has no foundation of values. 

 Here the definition of sociopath:   " A sociopath can be defined as a person who has Antisocial Personality Disorder. This disorder is characterized by a disregard for the feelings of others, a lack of remorse or shame, manipulative behavior, unchecked egocentricity, and the ability to lie in order to achieve one's goals."  (from wikipedia)  IMO, both Limbaugh and Trump manifest these characteristics.  Quite a pair......
