I'm a true believer. The revolution is coming. Both the right-wing and the left-wing are sick of the establishment. Neither Trump nor Sanders supporters believe the politicians have their best interests in mind. Anyone who can't see this tsunami of revolt is purposely closing their eyes to it. That's usually because they are a part of the system that Americans are now revolting against.
So, would it be nice if Bernie Sanders makes an epic comeback—and it would have to be epic—and wins the Democratic primary? Yes! Is it necessary? No! This is the beginning of the revolt against the establishment, not the end.
