People need to stop throwing around labels like "fascism" as if they're going out of business. Trump is populist...not exactly in line with the classic brand of populism though since e.g. European populists usually portray themselves as average Joes whereas Trump talks 24/7 about how his elite status.
Oh yes, but Trump's gauche displays of richness is much more appeals to the average Joe than Mitt Romney's hidden wealths or say the aristocratic background of David Cameron. Donald Trump, to your typical blue-collar worker, is what they would be like if they had money. None of that fancy elite stuff, just buy bigger and better and more ostentatious.
