The big problem, as the Vox article points out, and has been one of my greatest frustrations in trying to track this election, is that the exit poll results released to the media fail to provide any kind of cross-correlation. They tell you by age, by race, by sex, by income, by education level, but they don't tell you how it winnows down.
It turns out when you actually look at all the data, age is the most predictive factor, and it is not a sharp cutoof (although it is most dramatic if you compare the 50 or older v. the 29 or younger segment and ignore all that transitional stuff.
And does anyone cross-corelate this with any of the other relevant polls, like how people consumer news? Hah! But again, if you look at the PEW survey data, you will see huge differences in how all the major demographic groups find and consumer news, and how they discuss the issues with each other.
