Donald Trump has had an unusually long and dramatic tenure at the center of American politics. The reason is simple: Trump has an indomitable personality and an abiding refusal to kowtow to the establishment’s sacred cows. From the moment he entered the arena, he continuously provoked the ruling powers into a hysterical frenzy of breathless rage. Indeed, it’s hard to think of another American political figure who has caused more chaos, or faced more concerted and unscrupulous opposition.
