What is likely to happen when/if trump dies?

It must surely be imminent. He's not in the best health if the reports about him eating mcdonalds all the time are true. He's 79 which isn't that old but I dont see many fat, stressed 90 year olds on a mcdonalds diet.

Say he had a heart attack next week.. then what? Presumably Vance would take over as actual president, but I can't imagine anyone being as bad as him. Would the maga movement continue with a different cult leader? Do you think things would meaningfully change?
