They found that 64 percent of these voters had chosen Trump, while only 32 percent chose Clinton.
Was the turnout among white working class 96% indeed or did they only count those who showed up, with 6% voting third party? The 2016 total turnout was about 60%, if the rate was much higher for this demographics, it should’ve been explained.
The fallacy here is to assume that it was a split of votes for everybody eligible. But it only shows that “Clinton people” were less eager to vote than “Trump people”, not that Trump was overwhelmingly popular for whatever reasons.
