What does it mean to stand by Donald Trump? What does it feel like not just to live in his world, but to love it? I don't know. I don't live there. But then, neither do millions of the Americans who voted for him. As I try to imagine what they want from his presidency — what it might look like, what Americans might imagine it looks like, when America gets great again — I keep coming back not to the election itself, but to the movies.
