Before you waste your time I'll look for supporting articles from the media.
https://www.vox.com/policy-and-politics/2017/5/9/15592634/trump-clinton-racism-economy-prri-surveyFor example, if you follow the argument here they're downplaying the white working class vote for Trump. And there are other articles that try and do the same. However, the authors omit the most important figure which would prove their point: what percentage of the white working class actually voted for Trump? They didn't think that figure was relevant to their argument which is basically:
(1) we surveyed thousands of white working class people
(2) we found that trump-like views correlate to voting for trump
(3) therefore class has nothing to do with it, agreeing with Trump does!
(4) therefore, it's just bad people (dirty racists) supporting bad candidates
However down below they tabled their data, and depending on the question up to 68% of the white working class
expressed Trump-like views on a number of questions (while only 44% of college grads did), showing that the
entire argument is largely circular and meaningless. If an overwhelming number of people in one demographic express support for the ideas of a candidate isn't that
exactly the same as claiming that the candidate enjoyed support
from that demographic?
Instead they give us the argument that people in a specific social class who voted for Trump
agreed with him, therefore class isn't predictive: agreeing with Trump is. Which is both wrong and a circular argument.
