But to really get the feel for the Trump administration’s end, we must turn to the finest political psychologist of them all, William Shakespeare. The text is in the final act of what superstitious actors only refer to as the “Scottish play.” One of the nobles who has turned on their murderous usurper king describes Macbeth’s predicament:

Those he commands move only in command, Nothing in love. Now does he feel his title Hang loose about him, like a giant’s robe Upon a dwarfish thief.

And so it will be for Trump. To be clear, these are very different people. Macbeth is an utterly absorbing, troubling, tragic, and compelling figure. Unlike America’s germaphobic president, who copped five draft deferments and has yet to visit the thousands of American soldiers on the front lines in Afghanistan or Iraq, he is physically brave. In fact, the first thing we hear about him is that in the heat of battle with a rebel against King Duncan (whom he later murders) Macbeth “unseamed him from the nave to th’ chops.” He is apparently faithful to his wife, has a conscience (that he overcomes), knows guilt and remorse, and has self-knowledge. He also has a pretty good command of the English language. In all these respects he is as unlike Trump as one can be.

But in the moment of losing power, the two will be alike. 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. For now, admittedly, there are those who still court his favor—Senator Lindsey Graham, for example, once the trusty vassal of Senator John McCain, the bravest of warriors and noblest of dukes, seems to have switched his allegiance from his dying lord to the swaggering upstart aged prince. But that is about ambition, not affection.
