The proper course of action before the 17th Amendment and now with the Electoral Collage is for states to ‘bind’ the legislatures and now the Electors to the will of the voters. The Electors are not to have any say in who they elect other than to follow the will of the voters.
So, if on Thanksgiving the President-Elect rapes a nun and strangles a puppy, the electors have no choice but to vote for him in the election in December?
