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…
Maybe, but I imagine the Secret Service has a drone-attack plan. I would guess that most of D.C. is probably a no-fly zone for drones, and they probably lock down the White House it anyone violates it. I think as long as he continues to split his time between Mar-a-Lago and the White House, Trump is relatively safe.
If he starts doing more speaking tours, though, that might make him more vulnerable. There’s also a staggering amount of disorder and incompetence because of his attacks on federal workers and his terrible cabinet appointments, so I guess it’s possible he’s already opened himself up to security risks. Who knows.
