This is a false narrative of the polls as they were taken, as the election occurred, and how people reacted to it. It’s just as much bunk as both the lay and expert interpretation of the polls generally were during with the election.
This commenter is much more perspicacious about what really occurred and the issues involved.
Another relatively-undiscussed factor is that the polls and all the reporting about them affect how people vote — and if they do so or not.
No matter how much analysis or calculus you throw at that sort of problem, it won’t get you close to an answer.
The narrative that the polls were not wrong is used by Clinton supporters to show (somehow) that she “really” won or should have or something — I don’t really understand it. What I linked to is just a more subtle version of this and just as much garbage as the rest.
