And the source of allegiance? We’re supposed to believe that Trump’s support stems from economic stagnation or dislocation. Maybe some of it does. But what Trump offers his followers are not economic remedies — his proposals change daily. What he offers is an attitude, an aura of crude strength and machismo, a boasting disrespect for the niceties of the democratic culture that he claims, and his followers believe, has produced national weakness and incompetence. His incoherent and contradictory utterances have one thing in common: They provoke and play on feelings of resentment and disdain, intermingled with bits of fear, hatred and anger. His public discourse consists of attacking or ridiculing a wide range of “others” — Muslims, Hispanics, women, Chinese, Mexicans, Europeans, Arabs, immigrants, refugees — whom he depicts either as threats or as objects of derision. His program, such as it is, consists chiefly of promises to get tough with foreigners and people of nonwhite complexion. He will deport them, bar them, get them to knuckle under, make them pay up or make them shut up.

That this tough-guy, get-mad-and-get-even approach has gained him an increasingly large and enthusiastic following has probably surprised Trump as much as anyone else. Trump himself is simply and quite literally an egomaniac. But the phenomenon he has created and now leads has become something larger than him, and something far more dangerous.
