Sure, there was the attempted assassination of Reagan and the fears for Obama as the first black President, but in those cases it was a lone nutter rather than a conspiracy.
How long can Trump crash the market before an angry billionaire decides to take him out? The remaining Koch brother is already pouring money into legal challenges against Trump…
If that’s really their plan, they’ll have a rude awakening. They created this monster, and you don’t replace the person at the center of a cult of personality that easily.
That’s why they can’t go with the obvious route of saying he has dementia issues–the cult wouldn’t hear of that. But he can conveniently have a debilitating event or illness. Sure, the cult will have conspiracy theories, which is why they have to be sure to make it look plausible. But even if they have to resort to him having an “unfortunate accident”, there’s nothing the cult can really do about it, he’ll be gone. He’s just too unpredictable and uncontrollable for them to let him keep going rogue so much. Destroying the global economy and causing a worldwide depression is not part of their plans.
