Long before this even, Trump's own niece predicted he will do all this .. ..how did she know? She is a qualified psychologist who warned about Trump. It is utterly dangerous if her warnings are not heeded.
The founding fathers of USA knew that one day a demagogue will emerge who can sway the peopleĀ and endanger the country and world. Hence they put in place a system to check such a leader. He has broken the law and the legal system is handling him.
He will have followers because he knows what they want and lure them to support him.
