Can confirm. Second time in our lifetimes that the winner actually got fewer votes than the loser, though I guess that's just the system over there.
Next year we get to see this game played by a whole bunch of major European countries instead all getting the chance to vote for their own demagogues, so that'll be fun. If Marine Le Pen wins in France we may be looking to Donald Trump and Theresa May as the "liberal" voices on the UN Security Council.
Detailed thoughts, feel free to tl;dr these -
The next couple of years will be interesting from a US perspective. The Supreme Court is probably the biggest issue - if Trump appoints ultra-conservative justices, and assuming the Republicans continue not to do their job and ratify Obama's nominee (they're meant to be there to block massively biased or incompetent nominees, and they're instead blocking an overqualified moderate in the hope they can get their own guy on after Trump gets in) then it only needs one of the two elderly liberals (Ruth Bader Ginsburg, 83, or Steven Breyer, 78) to die and the court becomes massively conservative, which would probably deepen a lot of the social divisions between blue and red states by kicking issues like the legality of marriage equality and abortion back to being state-level decisions. Trump has said he doesn't really want to overturn marriage equality, but he does still apparently want to overturn Roe v. Wade, the SCOTUS decision that legalised abortion in all states.
In other areas, I suspect that Trump will try and "take action on immigration" which will cost many, many billions and do absolutely bugger all beyond make a few people's lives armadillotier. I'm very worried about what he'll do on climate change targets, especially given literally none of his advisors seem to think energy efficiency is worth doing (which is dumb; even if you believe global warming is a hoax, which is a silly position to start with, getting less reliant on fossil fuels is a long term no-brainer simply from an economic competitiveness standpoint). I think he'll back down on things like NATO and will be railroaded into a fairly status quo foreign policy strategy. Trade could be more interesting, but again I think his advisors may be bright enough to stop him entering trade wars. The thing that seems to have most gone out the window is being "anti-establishment" and "draining the swamp", given that literally the most insider-y insider in the GOP, head of the RNC Reince Priebus, has just been appointed as his chief of staff. Also his transition team is basically comprised of corporate lobbyists so far.
Short of a Dem landslide in 2018, and even with that as the Dems have to play a lot of defence in the 2018 senate races and the house is rigged to hell, he also may well have both houses of Congress with his party for a full four years, which will be unusual for a modern president. How well Trump will get on with the GOP remains to be seen - the appointment of Priebus may indicate that he's actually going to more or less let their insiders run things, though I may be wrong.
