Election Results 2016: Only 112,000 Voters Gave Us President Trump (heavy.com).

Beyond the tea leaves and wringing of hands: yes, Trump is laughably bad, yes, there is an underclass that would rather complain than get to work; but the explanation is readily at hand: the system is so broken it could only field Ms Clinton, and not enough people could get off their asses and vote for her. The result is still terrible.
