The reality, of course, is that what happened does not fit into a media-ready soundbite like "Trump voters are racist", "Hillary is a woman" or "Forgotten Middle America".
The reality is a complex mixture of some or all of the soundbites being thrown around:
A big portion of Americans (of
people) are racist, are sexist, are bigoted in some way, and Trump legitimised their views.
An even larger percentage of people are ignorant, and can easily be made scared by the threat of the other.
A big portion of Trump voters are rural working class people who have been left behind by policies that logically, but somewhat blindly, favour cities, where 80% of the population live - a number that will still grow.
A significant portion of democrat voters stayed home compared to Obama, likely due to lack of enthusiasm for Hillary (and some of that aforementioned inbuilt sexism).
Third party voters and spoilt ballots, on balance, probably would've tipped it back toward Hillary.
Etc, etc.
