Are you serious the guy literally lived out of a penthouse in Manhatten most of his life not to mention a place he literally calls the 'Winter Palace' among his many other homes.
Doesn't make him an elitist. If anything, he was known to not be a part of the Manhattan rich man scene and was more known for being among the common people. It's one of the reasons he was able to connect to the midwest/South so easily despite being a Manhattan billionaire.
Did Trump have any billionaire supporters? I know there was Carl Icahn. Cuban semi-supported him for a bit. Woody Johnson?
Yes! Yes it does.
Also, conmen always have the ability to connect.
As for billionaire supports. Gee how 'bout Rebekah F*&(ing MERCER.
