The title is pretty much self-describing. I have no idea who the actors are, and it might have been a comedy - I only vaguely remember it as the last time I saw it was 4 or 5 years ago. It came up in a conversation, and I want to rewatch it, but I have no idea how to find it.

This sounds like the 1997 post-apocalyptic Kevin Costner film The Postman based on the novel of the same name by David Brin.
In the novel and movie after an unnamed apocalyptic event a nomadic drifter who lived stumbles across the uniform of an old United States Postal Service mail carrier. He tries to survive by masquerading as a Postman representing a re-constituted United States. Due to his convincing acting, he doesn't actually become POTUS. But, eventually,
he unwittingly inspires hope through an empty promise of a "Restored United States of America". The myth of the reconstituted U.S. grows and becomes its own reality driving the actual rebuilding of the country.
Below is a picture of the movie playbill.
