Some have suggested that Donald Trump is a would-be tyrant. I would say no, not in the full-blown sense of a Hitler or a Stalin. He has no utopian blueprint he intends to impose on America by force. Ancient writers would probably have called him a demagogue. For them, demagogues mirrored the worst aspects of democracy. They incited the mob against their betters. Braggarts with a love of wealth and pleasure, they epitomized the most vulgar kind of behaviour. Does Mr. Trump stand for coherent policies? Despite flip-flops and vagueness, I think he does. It's just that he combines them in a way not done by anyone before, at least not within living memory. As a nativist, protectionist, fan of big government and quasi-isolationist (he would annihilate the Islamic State, but withdraw from the North Atlantic Treaty Organization and the Pacific), he is the anti-Ronald Reagan.
