Good Lord indeed. That’s some cognitive dissonance if I ever saw any. They could vote either way, for an avowed socialist or a committed capitalist, not to mention all the other issues on which they’re miles apart? Charles Manson was “anti-establishment” too, but I think I’d need a little more to vote him into public office.
They both preach economic protectionism, so it makes perfect sense.
They see Clinton as just another DC insider, who will spout all the right words, but after the election will just go back to the job of enriching her fellow insiders.
Their vote for Bernie is rebellion against the political class. They are saying "ENOUGH!".
They see Trump as another person who has no loyalty to the DC political class, and thus as a way to rebel against the political class. Thus we may see a bunch of "Trump Democrats", just like we say a bunch of "Reagan Democrats" crossing over some decades ago.
