The only fly in this ointment of a scenario is that, if Trump dies in a state of grace with the base, he dies a martyr, he becomes a saint to the movement, and the charlatans who were in his inner circle at any point will jockey for power to become the new leaders of that movement, and it might work because anyone who was close to Trump would be akin to being an apostle. Hell, it might even be Junior. The inheritors don't have to share his unique brand of charisma. They will need only to have been within his inner circle to qualify. And who knows, there might even be a bit of internecine murder at the top, a la Trotsky or Röhm, which would be a total bonus.
