I read an article recently by a Sociologist about this. Don't remember where, I cruise a lot of internet. His take was that they know about the lies, but ignore them and only respond to the dog whistles or talking points that they want to hear. To me, it's just like a religious huckster; some people just want to be in a crowd that believes. Example- the chump at one of his rallies in '16, "I've got the words...", crowd gets excited, "I've got the BEST words!", and the crowd goes nuts. 
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
