These folks have always been present in the United States. But Trump awoke (oh, that word) them. Where have they been all these years?
What this reminds me most of is the movie Night of the Living Dead. Let me explain. From the film's Wikipedia page:
https://en.wikipedia.org/wiki/Night_of_the_Living_Dead"Radio reports explain that a wave of mass murder is sweeping across the East Coast of the United States. Ben finds a television, and he and other occupants of the house watch an emergency broadcaster report that the recently deceased have become reanimated and are consuming the flesh of the living. Experts, scientists, and the United States military fail to discover the cause, though one scientist suspects radioactive contamination from a space probe which was blown up in the Earth's atmosphere."
Trump is the space probe. His radioactivity has reanimated the dead into zombies. Idiocracy? How dare you insult idiots like that. This is
Zombiocracy.
