It's worth reading the whole article because there's many amazing quotes. But the best part comes at the end:

In the basement, I smiled and said hello. She (Jill Biden looked back at me with a confused, panicked expression. It was as if she had just received horrible news and was about to run out of the room and into some kind of a family emergency. “Uh, hi,” she said. Then she glanced over to her right. Oh …

I had not seen the president up close in some time. I had skipped this season’s holiday parties, and, preoccupied with covering Trump’s legal and political dramas, I hadn’t been showing up at his White House. Unlike Trump, he wasn’t very accessible to the press, anyway. Why bother? Biden had done few interviews. He wasn’t prone to interrupting his schedule with a surprise media circus in the Oval Office. He kept a tight circle of the same close advisers who had been advising him for more than 30 years, so unlike with his predecessor, you didn’t need to hang around in West Wing hallways to figure out who was speaking to him. It was all pretty locked down and predictable in terms of the reality you could access as a member of the press with a White House hard pass.

I followed the First Lady’s gaze and found the president. Now I understood her panicked expression.

Up close, the president does not look quite plausible. It’s not that he’s old. We all know what old looks like. Bernie Sanders is old. Mitch McConnell is old. Most of the ruling class is old. The president was something stranger, something not of this earth.

This was true even in 2020. His face had then an uncanny valley quality that injectable aficionados call “low trust” — if only by millimeters, his cosmetically altered proportions knocked his overall facial harmony into the realm of the improbable. His thin skin, long a figurative problem and now a literal one, was pulled tightly over cheeks that seemed to vary month to month in volume. Under artificial light and in the sunshine, he took on an unnatural gleam. He looked, well, inflated. His eyes were half-shut or open very wide. They appeared darker than they once had, his pupils dilated. He did not blink at regular intervals. The White House often did not engage when questioned about the president’s stare, which sometimes raised alarm on social media when documented in official videos produced by the White House. The administration was above conspiratorial chitchat that entertained seriously scenarios in which the president was suffering from a shocking decline most Americans were not seeing. If the president was being portrayed that way, it was by his political enemies on the right, who promoted through what the press office termed “cheap fakes” a caricature of an addled creature unfit to serve. They would not dignify those people, or people doing the bidding of those people, with a response.

For many inclined to support the president, this was good enough. They did not need to monitor the president’s public appearances, because under his leadership the country had returned to the kind of normal state in which members of a First World democratic society had the privilege to forget about the president for hours or days or even weeks at a time. Trump required constant observation. What did he just do? What would he do next? Oh God, what was he doing right at that moment? Biden could be trusted to perform the duties of his office out of sight. Many people were content to look away.

My heart stopped as I extended my hand to greet the president. I tried to make eye contact, but it was like his eyes, though open, were not on. His face had a waxy quality. He smiled. It was a sweet smile. It made me sad in a way I can’t fully convey. I always thought — and I wrote — that he was a decent man. If ambition was his only sin, and it seemed to be, he had committed no sin at all by the standards of most politicians I had covered. He took my hand in his, and I was startled by how it felt. Not cold but cool. The basement was so warm that people were sweating and complaining that they were sweating. This was a silly black-tie affair. I said “hello.” His sweet smile stayed frozen. He spoke very slowly and in a very soft voice. “And what’s your name?” he asked.

Exiting the room after the photo, the group of reporters — not instigated by me, I should note — made guesses about how dead he appeared to be, percentage wise. “Forty percent?” one of them asked.

“It was a bad night.” That’s the spin from the White House and its allies about Thursday’s debate. But when I watched the president amble stiffly across the stage, my first thought was: He doesn’t look so bad. For months, everything I had heard, plus some of what I had seen, led me to brace for something much more dire.

We're sooooooo fucked lmao
