Bernie definitely aroused a lot of the left. Progressives. Democratic Socialists. Heck, just plain "Socialists." Trump is arousing the right wing (alt- or not), the fascists, the racists.
Bernie was never going to become president this year. Neither is Trump. This year. But Bernie's base will be a powerful progressive organizing resource for years to come. I am afraid Trump's base will also become a powerful weapon aimed right at all that is decent and good about this country.
It would be more fun to watch what happens next if I didn't have to live it.
