It was also peculiarly desirable to afford as little opportunity as possible to tumult and disorder. This evil was not least to be dreaded in the election of a magistrate, who was to have so important an agency in the administration of the government as the President of the United States. But the precautions which have been so happily concerted in the system under consideration, promise an effectual security against this mischief. The choice of SEVERAL, to form an intermediate body of electors, will be much less apt to convulse the community with any extraordinary or violent movements, than the choice of ONE who was himself to be the final object of the public wishes. And as the electors, chosen in each State, are to assemble and vote in the State in which they are chosen, this detached and divided situation will expose them much less to heats and ferments, which might be communicated from them to the people, than if they were all to be convened at one time, in one place.

Nothing was more to be desired than that every practicable obstacle should be opposed to cabal, intrigue, and corruption. These most deadly adversaries of republican government might naturally have been expected to make their approaches from more than one quarter, but chiefly from the desire in foreign powers to gain an improper ascendant in our councils. How could they better gratify this, than by raising a creature of their own to the chief magistracy of the Union? But the convention have guarded against all danger of this sort, with the most provident and judicious attention. They have not made the appointment of the President to depend on any preexisting bodies of men, who might be tampered with beforehand to prostitute their votes; but they have referred it in the first instance to an immediate act of the people of America, to be exerted in the choice of persons for the temporary and sole purpose of making the appointment. 
*** 
All these advantages will happily combine in the plan devised by the convention; which is, that the people of each State shall choose a number of persons as electors, equal to the number of senators and representatives of such State in the national government, who shall assemble within the State, and vote for some fit person as President. Their votes, thus given, are to be transmitted to the seat of the national government, and the person who may happen to have a majority of the whole number of votes will be the President. 
*** 
The process of election affords a moral certainty, that the office of President will never fall to the lot of any man who is not in an eminent degree endowed with the requisite qualifications. Talents for low intrigue, and the little arts of popularity, may alone suffice to elevate a man to the first honors in a single State; but it will require other talents, and a different kind of merit, to establish him in the esteem and confidence of the whole Union, or of so considerable a portion of it as would be necessary to make him a successful candidate for the distinguished office of President of the United States. It will not be too strong to say, that there will be a constant probability of seeing the station filled by characters pre-eminent for ability and virtue.
Alexander Hamilton, explaining the purpose of the Electoral College in Federalist No. 68.

Never in American history has a president-elect presented more conflict of interest questions and foreign entanglements than Donald Trump. Surely, electors have a constitutional duty if, after the popular vote but before the electoral vote, there emerges credible evidence that they are electing someone who is constitutionally ineligible to serve as President. 
As we know from the Federalist Papers, the Framers created the Electoral College to be more than bean-counters, to exercise actual intelligence and discretion. Otherwise, the Electoral College would not need to vote in person at public proceedings, complete with deliberations on the merits of the candidates, and the Secretaries of State throughout the country would simply certify the results and send them on to Congress. The Electoral College is in the Constitution for a reason, as an essential check and balance of power.
