Don't worry.
If Nazis can keep coming back (Since the 1920's), Donald Trump can come back.
I'm afraid folks are not learning the right political and moral lessons staring them in the face about how evil the establishment has been for centuries, how it paved the way for Trump to become president, why it refuses to change, and how the next president could be even more virulently fascist.
  And seeing the corporate establishment go so far down the muddy slope of fascism, who knows but the next president might be more reprehensible.
