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…
MAGA is pretty much entirely a cult of personality. Take out the Jim Jones, and they tend to go back into hiding. That’s the only hopeful part of all of this is that when Trump finally dies (by any means necessary), I’d bet everything that MAGA goes with him. Or at least as a political force. Hillibillies are still gonna hillbilly, but without Trump to embolden them, they’ll go back to ranting about 'libs after finishing up fucking their cousins and nothing more.
