A tyrant is unloved, and although the laws and institutions of the United States have proven a brake on Trump, his spirit remains tyrannical—that is, utterly self-absorbed and self-concerned, indifferent to the suffering of others, knowing no moral restraint. He expects fealty and gives none. Such people can exert power for a long time, by playing on the fear and cupidity, the gullibility and the hatreds of those around them. Ideological fervor can substitute for personal affection and attachment for a time, and so too can blind terror and sheer stupidity, but in the end, these fall away as well.

And thus their courtiers abandon even monumental tyrants like Mussolini—who at least had his mistress, Claretta Petacci, with him at his ignominious end. (Melania’s affections are considerably less certain.) The normal course of events is sudden, epic desertion, in which an all-powerful political figure who loomed over everything is suddenly left shrunken and pitiful, a wretched little figure in gaudy robes absurdly too big for him, a figure of ridicule as much as, and even more than, hatred.

This is going to happen to Trump at some point. Of the Republicans in Congress it may be said of most of them: Those he commands move only in command, nothing in love.
