[Theoria]

Citizens do not have the right to vote for electors, who in turn are not obligated to vote in the peoples’ interest.

The founders properly counted on state officials to choose electors who would comply with the state's wishes. Suppose a purple state votes Trump, but the state party is RINO and some of their electors flip.

This last and final casting of EC votes also allows electors to correct for a unique instance such as: Hillary wins, but its discovered after the Nov. election that she committed treason and sold secrets to Putin. Electors thankfully flip.

In an instance similar to this treasonous scenario just described, I'd defer to impeachment, rather than to the electors. Electors can be bribed and leave the building, never to be seen. Stakes are high, bribes could be monstrous, so even Republicans could succumb.
