The only silver lining to Biden’s painful performance? US voters had already made up their minds | Emma Brockes

Even Trump's usual lies could not distract from the president's decrepitude. But these debates don't move the needle

Who could have foreseen that the scariest thing about the presidential debate on Thursday night wouldn't be the lies, the bombast or the threats to democracy, but the spectacle of Trump's slightly wolfish restraint. Heading into the encounter, Democrats felt the kind of anxiety more usually endured before watching a child perform, with that same crushing sense of raw emotions. That Trump barely mocked Biden, or went after his age or his son, seemed less rehearsed than a shrewd response to what all of us were seeing: a president so compromised that all Trump had to do was grin, lean back and let the optics work for him.

And still, despite the evidence, it feels wanton to say this. Biden, whose voice was hoarse from a cold, rushed his delivery, fought to find words and stumbled in a style not entirely new to him. The difference on Thursday night was one of degree. Oh my God" was the general consensus, texted around the country, when the debate opened in Atlanta. While Trump's remarks were predictably ludicrous, full of lies and inflated claims, nothing he said could distract from the image of Biden saying sensible things in a manner so crepuscular that the entire event jumped from politics to tragedy. It made me think of a line from Rilke: It had almost hurt to see."
