#1: Only if their state had *already passed* such a law regarding their EC votes.
#2: Only if their state voted *opposite* to the majority popular vote of the US.

I am certain that if the compact rules seemed likely to result in anyone being elected who would not have been under the current rules, there would be lawsuits and disinformation meltdowns and bribing of / threats to EC members, all in vast quantity. The majority of voters were never asked about their state joining the compact and probably few understand what the consequences could be. And Republicans are far more opposed to it than Democrats.

Doesn't mean that it's not worth a try, and maybe the new Democratic trifectas will go for it. But I agree an amendment would be better. Just, much, much harder to get passed.

I'm also in favor of yanking the disproportionate EC voting power of smaller states, which is even more difficult. The only plausible path I see short of an amendment would be making the size of Congressional districts much smaller, expanding the House to say a couple of thousand reps. They might have to hot-bunk for a while but I understand there's an entire Ballroom under construction where they could be stuffed. This would dilute the extra weight given in the EC by Senators (there also should be fewer Senators in smaller states, but that obviously could never get adoption by enough states).
