Elon Musk has been inescapable in this election. How could he affect the results?

Less than a month before the presidential election, Elon Musk has made himself a near-constant presence in the race. On social media, he posts AI-generated images attacking Kamala Harris. The billionaire CEO of Tesla and SpaceX has emerged as a unique influence on the campaign in ways that set him apart from even the most politically active billionaires and tech elite. He is all at once a vocal Trump surrogate, campaign mega-donor, informal policy adviser, media influencer and prolific source of online disinformation. At the same time, he is the world's richest man and the owner of one of the United States' most influential social networks, while also operating as a government defense contractor and wielding power over critical satellite communications infrastructure.
