Mr. Trump is a) a Snake Oil salesman and/or b) a faith-healer.  He has brought his skills to the political arena and it's working.  Don't waste your time trying to understand his "positions" on the crucial issues of today.  Don't bother trying to understand what "Make America Great Again" means.  Mr. Trump isn't selling substance, he's selling faith.  He's selling his followers the belief that his Trump Elixor is the panacea for all that ails our country.  

His appeal is visceral, not intellectual.  His message is emotional, not rational.  He's offering voters the opportunity to "kick the dog" of today's politics; to vent the frustration and angst they might hold.  He offers the opportunity for his followers to "get back" at whomever they feel caused  their disaffection

He sells charisma....the faith that he and his secret elixor will work to "Make America Great Again".  Details? "I don't need no stinkin' details....I'll take care of those after I'm elected"   

He's a scary man.....
