Nixon was re-elected with a massive landslide, he was considered immovable.
Then came the Irresistible Force that was Watergate.
Even when ol' 'I Am Not A Crook!' boarded Marine One for the last time, Tricky Dicky's approval rating was 45%.
Guess whose is 30%: and halfway into his first term?
But if you want to see Xeno's Paradox demonstrated in the 21st Century: with the brakesless Mueller Train (before Robert pulls the eject lever prior to it's inevitably hideous but unmissable impact) Butt Secks, far be it from you to stop us revelling in the Schadenfreude show that'll be Donald Fart's ever-accelerating fall after reaching the absolute pinnacle of human ambition.
It can't happen? Remember Nixon: and think again.
Theresa May had a solid 25-point lead over Jeremy Corbyn on 7th June 2017; who could have consolidated her already unassailable power, his party not only made more the irrelevance they already were then, but he forced to resign. 'A week is a long time in politics' as MPs were wont to say. 8th June 2017 changed all that. The rest is history: and not just for her own party-based government majority, but the sole platform she was elected on: the delivery of 'Brexit'. The clusterfuck post-8th June 2017 culminating in even a soft 'Brexit's demise last week. Someone's gonna hate this Monday above all others.
Thatcher (*spit*) was as immovable as Terrie is now: yet, that... thing was booted out of No. 10. The EU - via the Maastricht Treaty - ultimately did for John Minor: if Terrie's a student of 20th Century political history, she should remember what happened next.
There's now a more-than extremely good reason why that Dead Woman Walking has the appellation 'Not' at the end of her name.
Nixon. Thatcher (*spit*). The moral of this story: All great powers fall.
No Exceptions.
