"Trump is America’s biggest comedian. His badinage is hardly Wildean, but his put-downs, honed to the sharpness of stilettos..."

"... are many people’s idea of fun. For them, he makes anger, fear, and resentment entertaining. For anyone who questions how much talent and charisma this requires, there is a simple answer: Ron DeSantis. Why did DeSantis’s attempt to appeal to Republican voters as a straitlaced version of Trump fall so flat? Because Trumpism without the cruel laughter is nothing. It needs its creator’s fusion of rage, mockery, and poisoned imitation, whether of a reporter with a disability or (in a dumb show that Trump has been playing out in his speeches in recent months) of Joe Biden apparently unable to find his way off a stage. It demands the withering scorn for Sleepy Joe and Crooked Hillary, Crazy Liz and Ron DeSanctimonious, Cryin’ Chuck and Phoney Fani. It requires the lifting of taboos to create a community of kindred spirits. It depends on Trump’s ability to be pitiless in his ridicule of the targets of his contempt while allowing his audience to feel deeply sorry for itself. (If tragedy, as Aristotle claimed, involves terror and pity, Trump’s tragicomedy deals in terror and self-pity.) Hard as it is to understand, especially for those of us who are too terrified to be amused, Trump’s ranting is organized laughter. To understand his continuing hold over his fans, we have to ask: Why is he funny?"

Asks Fintan O'Toole, in  "Laugh Riot/To understand Trump’s continuing hold over his fans, we have to ask: Why do they find him so funny?" (NYRB).

Maybe that's behind a paywall, and you can't read O'Toole's answer. Maybe you can answer his question on your own. I can't quote the whole thing.

I'll quote 2 beefy sentences:

Joseph Brodsky "used to appall his students by requiring them to memorize something like a thousand lines each semester."

"He felt he was preparing them for the future; they might need such verses later in life. His own biography provided a stirring example of the virtues of mental husbandry. He’d been grateful for every scrap of poetry he had in his head during his enforced exile in the Arctic, banished there by a Soviet government that did not know what to do with his genius and that, in a symbolic embrace of a national policy of brain drain, expelled him from the country in 1972."

From "Why We Should Memorize," by Brad Leithauser.

(In 1972, Brodsky became the poet in residence at the University of Michigan. I was a student there at the time and remember a grand assembly with Brodsky received as a great hero.)
