You are correct. The selection process is constitutional. Article 2 Section 1 reads “Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors”. If the states want to throw away their power and give the electors to the majority vote (fraud) winner, then they can.
However, I believe forcing the electors to vote for a certain candidate is unconstitutional.
If this the law being passed that is a pact between different states, then it isn’t unconstitutional. If it is just a law stating that Massachusetts’ electors will be selected based on the winner of the national popular vote, then it is constiutional. Pretty strange they would want their electors to possibly vote against the wishes of their own citizens, though.
