Clearly, campaign time is over and reality is slowly creeping in and there are promises he can't keep:
-Climate Change
-Repealing Obamacare
-Prosecuting Hillary
-Building"the"wall
-Withdrawing US funding to NATO
Just to name a few.

I don't even think the trade alliance he has promised to cancel within his 100 days will work. The reason these nations are exporting so much to the US hence the trade imbalance is because they cannot manufacture the products cost efficiently at home. Their cost of labour is too high. Paying a casual labourer in manufacturing min $8 per hr is uncompetitive. The only manufacturing businesses that can survive n the states are the ones relying heavily on machines/robots and not human which defeats his promise of creating jobs. Factories will just bring in more machines. Another concern is his seemingly lack of enthusiasm in the media and tech sectors, these are sectors that rely heavily on human resource. He should definitely put more focus there in my opinion to attract jobs especially for the youth.

Anyway, either Trump will be one of the greatest presidents America has ever had or the biggest joke. There's no in-between.

I think it's not impossible to overturn the election but its very improbable that this will happen!
