It feels strange to suggest that the second-most memorable thing that happened on a stage in Butler, Pennsylvania, this year was the former president of the United States getting shot in the face. But if Donald Trump wins the presidential election, the image that will be seared in my mind is that of the world’s richest man, Elon Musk, jumping around the same stage a few months later—eyes weirdly vacant, a black MAGA hat splayed awkwardly on his head, his legs and arms outstretched in the shape of a knotted and overgrown X. Musk had been a public Trump supporter since the summer, and a not-so-subtle conservative sympathizer for far longer.
