vicissitudes, literally none the shit on your list was policy-based except I guess tenuously the notion that "ideologically" they don't have representation in the main parties, and they're only the same on that in the sense that they're completely different. Marriage equality is a non-issue now - you'll get a few who campaign on a constitutional amendment, but it's really a non-starter and even most GOP voters know that. Literally nobody is going to say "they would have been in Iraq" now it's obvious how much of a fuck-up it was, it's a benefit of hindsight thing. Clinton also wants to try and get rid of Citizens United, she just thinks she can't win without PAC money. I think she probably could, but I don't blame her for thinking otherwise, this is an unusual election and typically money has had much more importance. She's also been pushed into an anti-TPP position - thanks to Sanders, but still there now. If you even read the Trump article on healthcare you posted, he's essentially expanding Medicare to the poorest, rather than implementing a comprehensive single-payer scheme. In that respect, Trump's position is closer to Clinton's, not Sanders.
If you're looking for issues where Trump and Sanders have more overlap than Clinton and Sanders, you're looking at just marijuana and maybe depending on how you interpret it taxes on Wall Street, which is a tiny part of the problem with Wall Street anyway, the main part being the horrific regulation in place. Meanwhile, you have to overlook the fact that Trump would essentially persecute Muslim Americans on a scale not seen since the Japanese internment camps, just to name one issue of many. Absolutely smh at the notion a Trump vote is anything like a Sanders vote.
