My take on this, once I researched it, is that it is one of those “be careful what you wish for things. That is, a state that votes overwhelmingly for candidate A, gives all their votes to candidate B, because B won California and NY and got the majority of popular vote.
This would, IMO, kinda tick off the voters in that first state. It also demonstrates why this whole thing makes no sense, unless your goal is to steal elections by going for voter fraud only in those states where you get more bang for the buck with illegals, etc.
And as I’ve said many times, WHENVER trump leaves, we will be on the cusp of the equivalent of the Russian and French revolutions - it will be nothing like the American revolution.

If that is what the compact does then it should be shot down. However, it would make more sense if the popular vote in a state that votes overwhelmingly for candidate 'A' be required to give all of their electoral votes to that candidate. It should not depend at all on the nationwide popular vote...which is what I think you are saying it does.
Voter fraud will no longer be necessary under this proposal.
All that will be necessary is for NY and California to deny Trump, or anyone else they choose, placement on their ballots.
Since there is no constitutional requirement for a Presidential popular vote election in the first place, and since States are free to appoint their Electors however their Legislature chooses to do so, I'm sure they could do this.
Trump got 7.5 million votes in NY and California in 2016. Prevent those votes from entering a mythical "national popular vote", and you guarantee the outcome.
No fraud needed.
