The electoral college has yet to vote.
This is exactly the kind of thing the institution was created to protect us from -- ill-considered actions by the voters; one of the critical flaws of democratic action by the masses. The wolves deciding what's for dinner.
The system allows for the EC to act on this by not voting him into the presidency. There are numerous strong reasons to do so.
There are 29 states (plus the District of Columbia) that require lockstep following of the voting public issue; they issue a small variety of rarely enforced punishments for electors that do not do so, including fines and misdemeanors. EC members have individually done this 157 times to date, so there's plenty of precedent on a per-elector basis.
Also... if they don't do this... then I submit that the EC has proved that the institution has no actual worth.
Another thing: this circumstance was brought about by a dissatisfied public. Imagine the levels of dissatisfaction as automation adds its impetus to the job losses we've already seen due to recent labor policies. Now consider the chaos Trump could add to the mix if he actually follows through on some of the things he said on the campaign trail.
Some of those include an increased willingness to use nuclear weapons; disruption of current trade patterns; economic problems (we're already seeing some of that, check the news on world financial market reaction this morning); Walking back major aspects of social progress - Roe v. Wade, LBGT rights, etc.; government using religion to select people for abusive treatment... It's quite a list. I find it a formidable counter-indication in terms of expecting the next four years to go well, and the follow-on effects may last for considerably longer than that.
Remember how long it took under the Obama administration to recover from Bush's bumbling economic moves? Then there's the whole question of who ends up in whatever supreme court seats go vacant. That alone could change the nation's path in many negative ways, as we have previously seen several times.
