For me, I'm hoping that Trump is a fascist. He can't come right out and run as a fascist, of course, but I am intrigued that he's doing so much to kiss up to veterans and the military. Fingers crossed, but I think it's possible if he were elected President, he would have the military cross the Potomac, march on DC and slaughter all of Congress and the Supreme Court.
However, if I were to answer your question like a normie, I would say that most people don't really care about experience. It ranks maybe 15th on my list. Many who post on this board would surely vote for Rubio ahead of the much more experienced Sanders, of course. Also, one could argue that Trump's executive experience is better preparation for the executive position of presidency than being a senator.
