Congress decides when the election of the Electors is by law according to the Constitution which they have done. The Electors will be chosen and they will then elect a President and Vice President in December. Regardless of Hillary being the candidate they pledged for or not or Mickey Mouse or Justin Beaver. They can vote for whoever they want unless their State Legislature requires them to vote for who the pledged for.
