get up there and have more charisma than him and make him the butt of so many jokes that everyone is straight up laughing at him.

That and be more of an outright Nazi than him. You forget that it's not just about charisma, it's about creating a white christian ethnostate. If you can out-Trump Trump, which inherently means amplifying Fascist rhetoric in a folksy charm, but also providing an entertainingly scathing critique of everything not white and rich, then yeah, you'll win. But otherwise the right will always vote for the biggest Nazi in the room.

Failure to recognize this is a failure to recognize how the right thinks. Fascism isn't the outlier in the American right, it is the norm. They just don't like calling it Fascism, they prefer traditional christian values.
