TL;DR - rig the presidential election system with fake comm's to the Associated Press.
How did Trump win is 2016 if the cheating system was so good, you ask? Well, I'm glad you asked. I happen to have a theory that should entertain your hat rack. And it's not simply 'overwhelm the polls'. He cheated. Legally. I racked my brain to figure out how one could throw the election of the president of the united states LEGALLY. It's simple. Dead simple. Single point communication weakness. Who calls the election? Associated Press. Who tells them what to call? I don't know. Someone does. In any case, control the individual who sends the instructions to the AP, or intercept and replace the communication to the AP. That's it. Election rigged. And it's legal because the AP isn't even legally part of the election system.
