We have a large crowd that cannot think for themselves and they will be used by whoever figures out how to cattle herd them. If you ever watched the show Walking Dead, think of how the characters send mobs of zombies ahead of them to hurt their living enemies. If you haven't seen the show, it describes how small groups of humans survive after society and our current social supports collapse. There are countless mindless zombies that will try to eat anyone alive they get near. People have broken up into small tribes and wind up fighting one another. Some groups are more moral than others. The easiest way to fight your competitors, is to divert a group of zombies at them and after they are weakened, move in for the kill.
The truth is, a large group of American voters are like the mindless zombies and no intelligent argument in favor of one candidate or another will move them. For some reason, we are afraid to call them idiots. Don't want to offend them, I guess. No need to worry about that - they aren't reading these articles.
