The working poor did not vote for Trump more than they didn't vote. But even if you break down the vote by income, more wealthy folk voted for Trump and poorer people voted for Clinton, but more importantly, most of them didn't vote because they reckoned that neither choice affected them. I never understood this argument that poor people voted in Trump especially because it does square with exit poll data.

I do think some people voted for Trump as essentially accelerationism, but unless the Democrats and the media apparatus succeed again in disenfranchising an actual left candidate in 2020 (which is always possible) the tide could turn.
