Here's what I think:
If Hillary wins:
Hillary is just as liberal, but weaker, both physically and in terms of influence, than Obama. Expect, in general, the status quo to continue. The only major change will be SCOTUS, which will automatically shift left because you know she's not going to nominate another Scalia to keep the court in the delicate balance it was in before Scalia died. Those filing lawsuits will be aware of this and stall any appeals to SCOTUS as long as they can. In lieu of using the courts, civil disobedience will become more common. Republicans will make gains in the 2018 elections.
If Trump wins:
He will use the office of the Presidency to enrich and glorify himself. Corruption, cronyism and political retribution will be the norm—and Congress will be more likely to go along with it. He won't nominate anyone on that list for SCOTUS, instead picking someone who promises favors to him. Democrats will be limited in how much they can gain in 2018 (they already held firm or gained in 2012, which built upon gains in 2006). The best case scenario is that Trump gets bored with the Presidency and resigns, in which case Mike Pence follows a more recognizably conservative path.
You beat me to it!
The only thing I'd add is that I see Republican voters conducting more Bundy-esque types of militant uprisings. I base this on how Trump and his supporters believe that 'the election is rigged'. If one believes this, then how can such a person accept a false result? And being armed means a belief, for many, that one can actually affect change.
Of course, with a Clinton, they'll be crushed... just like Waco. But I expect it'll take a few tries before the average Trump supporter will get the message. Then it will die down (pun intended).
And it will die down. For with federal control over Social Security and Medicare/Medicaid, the majority of those most likely to engage in unrest will have the threat of their retirement and healthcare removed. Most won't want to see it go.
