Yeah a big IF, but if he loses and were to bolt to a foreign country, regardless of us wanting to dunk on his intelligence, there really is a treasure trove of intel for any competitor nation out there with what we all suspect is Trump's casual engagement with the duties of his office and the information that naturally passes through the Oval Office and which one can assume the POTUS gets briefed on. Even certain regular daily protocols we might find innocuous at first glance could be exploited in ways we could never imagine by a hostile power. To put that in perspective there is literally a presidential poo collecting duty among the president's entourage. They collect the POTUS's **** when he's away from the WH on like foreign trips. Sounds nuts but there is a lot you could gather from medically analyzing the prez's poo, way more than anything revealed in any public medical records, which even under the most transparent of administrations is a bit of sham kabuki theater for the public.
Does the prez have allergies? Are they taking any kind of medications? If so, what are these meds proscribed for usually? Meds for a physical ailment or are these more associated with mental health? Any Illicit drugs? Are they an alcoholic? What's their general stress level? Genetic profile reveal any tendencies towards disease in the family? And more I can't think of off the top of my head.
Why bring up such an odd factoid? Because it illustrates how (In normal times.) tight as a drum the office of president HAS to be. The stuff we can't imagine as regular folk? Trust me, somewhere, at some time, there were multiple rooms across the world with really smart people thinking about the security of the POTUS. How to ensure it and how to undermine it. At one point either somebody said "Wait... What about the president's ****?" or word got to U.S. intel that a foreign power was trying to obtain the president's **** and there was, insane to think, an adjustment of protocols and security measures accordingly. There are secret parts of the POTUS's daily routine, info and updates, and methods, that countries' intel agencies around the world would salivate at the thought of getting even a hint of any specificity of, regardless how minor a detail.
And the real threat if Trump bolts is probably those in his entourage, like Miller, Kushner etc. He goes "in exile" and those folk are going with him. The thorough need to shake loose every possible security risk and poison pill left by Trump and his minions is going to be a huge priority once he is hopefully out, doubly so if he does decide to leave the country and flee what we all hope is likely prosecution and a public laying bare of all his corruption and criminal acts.
Which we have ample evidence of and not a single excuse not to act on.
