What if Hillary wins despite losing the popular vote?

[Seneca]

Here's the scenario

Election Night
Trump 47.4, 266
Clinton 46.7, 272
Johnson 4.2
Stein 1.4

CO, ME-02, NC, NE-02, NV and WI are close enough that recounts are ordered in all of those states. The recounts add marginally to Clinton's popular vote totals and flip NE-02 but have no effect on the outcome of the race. On December 15, the electors select Clinton as President-Elect.

How does the public respond? Given the Trump campaign's preemptive suggestions that the election might be rigged, it would seem that the spectacle of a minority-PV victory and multiple recounts might serve to "validate" those claims in the eyes of his supporters. Might we see a generalized breakdown of civil order, with mass shootings and bombings over the winter?

Highly unlikely. In fact, the opposite scenario is a lot more likely.

Democrats' advantage in the electoral college would suggest that a Democrat winning the EC with a slim minority of votes is more likely than a Republican doing the same.
