@Finn dAbuzz,
Quote: Trump received votes from people who had voted for Obama.
This was an interesting demographic. My purely anecdotal experience would suggest that a large proportion of these people were what we could call "unsophisticated" voters. These are people who might or might not have a party affiliation — if they do it's often the same as their parents. They don't vote in the midterms and seldom vote in local elections unless there's a hot button issue like school taxes. Some of these people have a very unrealistic idea of how Washington D.C. actually works and seem to feel that all we need to do is elect a president and he (probably not she) will be able to do all these great things for them. And then, when the delusion of a promised gravy train doesn't appear there follows a disillusionment, which often involves switching one's vote to the opposite party. "This'll show 'em!"
The Republicans in 2012 and of course Trump in 2016 made outright attempts to gain the votes of the disappointed and resentful. And of course H. Clinton wasn't the sort of politician who could really address this issue by deflecting criticism and making a case that Republican obstruction was at fault. She just sounded whiny. (Bill Clinton — cringe — when at the top of his game, might have been able to.)
Based on people I talked to during the Obama campaigns; having voted for Obama doesn't prove that someone is
devoid of racial prejudice, just that it isn't an all-consuming passion. Like the old guy who told me in '08, with a big smile, that he'd be "voting for the n****r", since he "always wanted to pick cotton". Or the "progressive" woman who wouldn't vote for Obama again in '12 because he hadn't lived up to her expectations of what a black male was capable of doing, having completely misread the guy — she assumed he'd be the Wesley Snipes of politics. I don't think Obama's victories show us to be a post-racial society, nor would I
completely discount "whitelash" as one of the factors giving Trump a majority in the EC. I agree that "racism" is not the sole, nor even the main, reason for his victory.
