If you're going to cherry-pick the information, then I could see that. Did you miss the part where it said that Democrats and Democratic-leaning independents (aka. Sanders supporters) made up 55% of non-voters?

Also, here's more on the "Never Hillary" crowd who contributed to Trump's win. 33% refused to support Clinton despite Sanders' endorsement:

And then there's this poll taken by Economist/YouGov on the eve of the election that indicated that 55% of Sanders supporters viewed Clinton negatively:

As for more recent events, consider how the far left has been echoing the alt-right mantra of the Ukraine being the bad guy, NATO being responsible for Russia's invasion, and leftist support for Putin:

Speaking of "referring to evidence" that doesn't support claims, remember that story about the People's Republic of Berkeley? It was the only thing you offered to contradict my findings, was immaterial, and the rest of what you offered was merely divergent opinion. If you're going to demand evidence, offer some that supports your argument that "something else is going on."
