Of course the Founders did not anticipate the rise of political parties. They expected electors to vote for men they knew from their own state mostly (so they put in the provision that they had to vote for at least one person not from their own state) and that the House of Representatives would pick the winner in most elections. Of course that has only happened twice but it could happen again if a third-party candidate got enough electoral votes to keep anyone from getting a majority. George Wallace thought he could do that in 1968.
What is the end result of 160 million sinners voting?
Barring a Constitutional amendment it can’t happen. The “compact” that some states (Maoist ones) have signed is unconstitutional unless it gets Congressional approval.
