TOI correspondent from Washington: Historians may someday conclude that US President Donald Trump’s greatest contribution to American political discourse was not immigration enforcement, or peace treaties, or even trade wars. It must have been a painstaking seminar how he coined the term “Dumocrats”.“In several interviews and speeches over the past week, Trump has revealed what he considers a linguistic breakthrough akin to the discovery of fire. “Do you know why I call them democrats?” He explained patiently about his weak political opponents. “Because they’re stupid.” Then came the etymology lecture which included the priceless claim that many people don’t know that the word dumb ends with b. On more than one occasion, the President has carefully walked his listeners through the spelling of simple monosyllabic words that three-year-olds would love to read, as if introducing cavemen to the alphabet. He once explained that “see” is spelled SEE, not SEA, and another time he said he had made the remarkable discovery that, like the United States, ours is spelled “US.” Late-night comedians reacted as if Diwali, Christmas, Hanukkah and the Super Bowl of jokes all rolled into one. One host observed that Trump was now explaining words the way a kindergarten teacher explains crayons to children. Another joked that America had somehow elected a president who could turn two-letter words into graduate seminars.Yet it was merely the latest installment of the longest-running comedy series in modern political history. Whereas previous presidents occasionally cracked a joke or two, Trump has turned the presidency into an industrial-scale content factory for comedians. Some nights, when most of America sleeps, the president begins a marathon social-media posting session that resembles a drunk uncle discovering a touchscreen for the first time.More than fifty posts were published in rapid succession on a recent evening. The resulting feed read less like a communication from the commander-in-chief and more like someone handing a smartphone to a simian. There were posts about judges, about elections, about television ratings, about construction projects and about people who are insufficiently grateful to them. He also posted AI-generated images of himself adding to Mount Rushmore, riding with George Washington and presenting himself as a superhero. Around post number 47, even loyal followers got lost on whether America was winning the trade war, building ballrooms, invading a country, or simply debating about renaming buildings.Trump’s construction obsession has become particularly notable. Now he discusses construction projects with the enthusiasm of a retired contractor who has cornered you at a party. Updates on the ballroom, reflecting the pools, fountains, expansions, additions, improvements, proceed in a torrent, bypassing China, Canada, Greenland, even Iran.No description of Trump’s comedy output would be complete without his enduring fixation with cognitive tests, a subject to which he returns with the persistence of a man who believes he deserves a Nobel Prize for identifying a camel in a picture book. While repeatedly boasting about passing the Montreal Cognitive Assessment, the President repeats parts of the test as if describing the moon landing. The joke, as stated in several comics, is that the test is designed not to identify geniuses but to detect signs of cognitive impairment and dementia. One comedian quipped, “It’s like bragging that you passed the breathalyzer.” Another compared it to a driver announcing that he had successfully stopped at a red light. Then came the spectacular finale of the Freedom 250 concert series to celebrate America’s 250th birthday. Organizers announced a lineup. The lineup immediately began to part. The cast retreated so quickly that the event began to resemble a lifeboat drill on the Titanic. Several artists said they did not fully understand the political nature of the program as they ran.Trump’s response was characteristically polite. Why not take the musicians’ place yourself? After all, they argued, he attracted bigger crowds than Elvis and did so without a guitar. So they replaced the concert with a MAGA rally featuring the one artist who never gets canceled: Donald Trump.
