The debate was not just a catastrophe for President Biden. And boy—oy—was it ever.

But it was more than that. It was a catastrophe for an entire class of experts, journalists, and pundits, who have, since 2020, insisted that Biden was sharp as a tack, on top of his game, basically doing handstands while peppering his staff with tough questions about care for migrant children and aid to Ukraine.

Anyone who committed the sin of using their own eyes on the 46th president was accused, variously, of being Trumpers; MAGA cult members who don’t want American democracy to survive; ageists; or just dummies easily duped by “disinformation,” “misinformation,” “fake news,” and, most recently, “cheapfakes.”
