The media's "angry, ignorant mouth-breather" stereotype of the Trump voter is no more than Lefty media spin. Since they do not talk to Trump voters, they will never report the reality. While working class white voters, male and female, might have given Trump his electoral edge, clearly large numbers of all sorts of demographics preferred him over Hillary. I did, and I do not think I am a knuckle-dragger.
Megan McArdle has a half-decent piece, Trump Voters Want Respect. Here’s How to Give It to Them, but it falls into the same stereotyping: sophisticated, educated elites vs. ignorant, feckless plebs referred to as "them." It is condescending and inaccurate.
If Megan wishes to contact me, I would be happy to introduce her to a goodly number of sophisticated, highly educated New York elites who were Trump voters - some enthused, some in the (political) closet, and some holding their noses but ok with it given the alternative.
