One thing that is indisputable, is that Trump is referring to other Americans as "his enemies"(see his New Year "greeting" tweet)....When you start calling others domestic enemies, you are entering into some very uncharted waters for a western democracy....

As many have pointed out, this frame of mind, is simply unsuitable for the US Presidency, or entirely suitable for a 3rd world despot.

For the near term, I see the Republican Party House members using him to sign their bills (repeal of the ACA, Medicare, etc.), etc. Trump is not one for details, and will essentially go along with what ever the last person to speak to him for more than five minutes told him.

But when Trumps actions start costing these people either financially or electorally, they will pull out all the issues (his conflicts of interest, etc.) they will ignore for now, and move to get rid of him.

Besides, I cannot see him being interested in the job for more than 12 - 18 months...
