I am by no means an expert on the economics of MAGA rallies, never having been to one, but I gather they work something like this:

You pre-register for tickets, anything from $10 to watch the event on TV outside the tent, to $5000 to get a selfie with Don Jr.

Once there, there will be auxiliary events that you can pay for separately. There will also be hundreds of hucksters peddling tee-shirts, flags, video cassettes, and other memorabilia.
