I see this as a win for the Constitutionalists but not a “defeat” for the anti-EC / popular vote folks. Their fall back position will be the compact to have their electors vote in accordance with popular vote. I belive the compact or agreement is unconstitutional as any such compact requires approval of Congress.
Ultimately, I see that as a bad thing as it disenfranchises the vast majority of voters. In my opinion, the electors should be decided on a per congressional district basis. Whoever wins a majority in the district gets that districts electoral vote. If no clear majority, a run off election held 30 days later, that does not accept or count write in ballots and only has the top to vote receiving candidates from the first election. This should establish a clear majority winner for that district.
The two state electoral votes SHOULD be awarded with 1 electoral vote going to the candidate that won the most districts in the state and the second electoral vote going to the candidate that won the most votes in the state. Ties for state votes should be decided by a unicameral vote of the Legislature or by the Govenor, according to state law.
Popular vote of whom? The nation? No, they are electors of a states’ constituency, not the nation at large. That would go beyond faithless to well past feckless. Whole states would be w/o representation if this ever happened.
