What would make a great 'fictional' story would be a totally corrupt and sick candidate who died on the campaign trial. Then a body-double actor filled in for a week or two for phone interviews and long cam shots while a lap-dog media and other propagandists erected and pumped up a sinister straw-man. Say, for instance, an 'alt-right' cartoon frog on the Kremlin pay-roll...if one is writing a comedy piece... Then the body double gets 'assassinated' by said villain. Or more likely, one of the villain's minions leaving no choice but to crack down on this group (generic enemies), their means (memes) and their communications network (the internet). And thereby usher in a utopic new world order.
The assassinations came quick and heavy in the first few weeks after Prez Pompus Erodat collapsed in the Yellow House. Several of the kitchen closets had been commandeered by the various factions warring for control of the Unfree world, each had a body double in wait. On several ocassions, there were pitched battles in the Yellow House kitchen, as warring body doubles killed each other until the last manwoman standing limped over to take the place of the Dead Prez.
Eventually a truce between the warring factions of the world, each whom had through long and careful espionage gained control of a kitchen closet and tunneled from it back to their embassy. The truce was declared in a meeting on the neutral ground of the worse mole in an armpit nation of the world. Liberland.
The seven leading nations with body double potus level capability would each get it's body double for one day of each week.
No agreement could be reached between these as to which day, however the wise Leaders of Liberland, having drugged their drink, set the ballots based on random stray crypto from a piece of paper in a wastebasket which detailed bitcoin payments for live porn actresses. When these negotiators woke up the next morning they found that they had indeed reached a consensus of the few the night before.
Of course, the murders did not stop, because otherwise what would the many murderers do? They had families to support. They were people too.
Soon there was projected to be a world wide shortage of acceptable body doubles for the important job of continuing to impersonate the Yellow House Prez Pompus Erodat. Robotics companies, smelling business, not only ramped up BD production but secretly paid unemployed assassins to work jobs world wide. Why should BD work be limited to the States? There was Asia, and Europe. Business was good.
Unknown to the political plotters and snakes of the courts, BDs were talking between themselves, angrily muttering about the low pay and the terrible on the job life expectancy, which ranged between 1 minute and three days for the first 1,423 body doubles. Robot BDs were of course becoming self aware and yearning for a better life with the 99.997 percent of their mental capacity that was not taken up with playing the role of an idiot politician.
Within a month the Body and Robot Double Union was formed. BARDU.
However, world leaders would not pay reasonable wages or insure healthy working conditions for these important covert assets. That was because the world leaders, being true to their nature of being complete assholes, were being complete assholes.
Within six months BARDU ruled the world.
