We Need to Have a Demagogue Detector

To avoid future threats to our democracy, we should develop something like an earthquake early warning system.  Donald Trump could serve as our model. We have seen this movie several times before.   If we can learn to pick up the plotline from seeing the previews, maybe we can avoid having to watch this movie unfold again. Once upon a time, we were taught to be wary of snake oil salesmen, traveling medicine men, card sharks, and other charlatans.  We need to revive the lost art of distrust.
