Interesting. I think a lot of that is very fair - some may be over the top and too far left in its viewpoint for a lot of Americans, but I think there's a general point to be made that in an election where a lot of key swing states went for Trump, Bernie may have been able to win them by appealing to the dissatisfaction of many people who've been fecked over in recent years.
I wonder if this is part of what we've missed when talking about Trump voters. Anyone who voted Bernie and would consider switching to Trump would be characterised as reactionary and anti-Clinton for the sake of it (and that's true to an extent), but it becomes more understandable if you're someone who's just felt failed by the system, and want something different. Maybe. I don't know, of course...I've never been there, so I might be talking out of my arse, but the impression I'm getting seems vaguely similar to some of the failures of Labour in the UK, wherein they're seeing parties like UKIP thriving in some of their heartlands because people don't feel they're doing enough.
I think part of the problem as well was the sort of condescending attitude sometimes shown to Bernie supporters after the primary. Granted, the absolute, sensible thing to do was get behind Clinton and rally for her to beat Trump, but anyone who argued that Sanders would've beaten Trump and had a better chance than Hilary was typically characterised as an idealist when it's now looking like it would've either been the case, or he'd have given a much, much closer race than Hilary did.
