While not a Republican by any means, I would certainly be considered on the right by most of the people here, and live amongst the Trumpers. Also, important to note I live in an area that features a heavy population of those sorts of Republicans, so take it with a grain of salt, but...

Having engaged quite a bit with Marx (and disagreeing pretty sustainedly on a lot of things), I respect on some level that his political project was about freedom, but worry about the people who run such systems.

The blue collar alliance, I think, exists because those right-leaners who like Bernie feel intuitively about him the way I do about Marx, and in this case, they agree with him on enough things that his personality (his personality!) is the thing that wins them over.

They trust the old socialist to speak his mind, if nothing else, which goes a very long way with them.
