That "Blame the Rich Whites" chart is completely meaningless.
Here's the chart that matters:
What this shows (and yes I realize this is the popular vote not electoral vote, but still):
A) Voter turnout was way way down. People don't show up to vote for candidates they greatly dislike.
B) Specifically, very few came out to support HRC. Fewer than half the number of voters who voted for Obama in 2008 voted for her this time. That is a complete rejection of her candidacy by the democratic base. Exit polls and anecdotal evidence seems to show this across the spectrum, from blacks and Latinos to white males to women of all stripes.
C) Based on the chart, Trump might look like he had steady Republican support, consistent with prior elections. But: we know that many white working class voters in states like the Midwest and North Carolina switched from having supported Obama to supporting Trump. So, what you can deduce, is that a good fraction of Trump's bar in 2016 isn't actually even the Republican base. A good part of that bar may, in fact, be the
Democratic base. Which is mind-boggling - but goes to show how tonedeaf the DNC was in coronating HRC when, very clearly, Bernie was turning out the crowds and hitting both the millennial and white working-class demographics.
My takeaway: Trump won only because Hillary lost. Voters NEVER like "third-term" presidencies. After a two-term president, elections more often than not seem to go to the candidate for change, not the candidate of continuity. (Again: what the hell was the DNC thinking?)
I'll also add one more important point. I myself voted for the candidate who I saw as the lesser of two evils. I think many many others did the same, but unlike me, they saw Trump as that person. I don't agree with it, but I can understand it. In other words, the important point I'd make is that Trump did not win on account of having revved up the racists and misogynists in society. He won in SPITE of that, only because he faced Hillary in the general election. I actually believe that if Trump had been a more "Presidential" candidate - more respectable, more hinged, just a little bit more policy-specific - he would have absolutely blown this out of the water. It wouldn't even be close. My hope is that Trump realizes this - that he realizes the race-baiting and erratic behavior didn't help him in the end. If he realizes that, then he will know to moderate himself in office.
I think everyone should go out and hug a Trump voter today - whether in person, or on Facebook, or by email, etc. I believe that many of them made a very difficult choice and are probably now equally nervous about what this all means. Living with uncertainty, as we all are now, is quite awful.
