Who said national law doesn’t exist? You break national law, decent chance you end up in prison. That’s real enough, even if not perfect. But what happens when you break international law? 99% of the time, nothing. And in the rare cases something does happen, it’s usually not really because of the law. It’s because countries have incentives independent of the law that make them enforce it. Often, the enforcement being illegal as well. That’s not really law, that is a bunch of outlaws shouting at each other with pipes in their hands, threatning each other.



Because without 270 votes, this could result in states that sign having even less impact, resulting in them not signing. As an example, imagine it goes into effect immediately. Now as a candidate, you have two options.
Option 1: Campaign and make promises in a state that signed and the only thing you get is more overall voters to win the popular vote and therefore the electors of states that signed. But winning the popular vote is not enough. You still need electors from other states.
Option 2: Campaign and make promises in states that did not sign. Convincing voters here not only gives you votes for the popular vote, but also for the states electors. So you gain votes both towards the electors of states that signed and this state that didn’t.
Now where would you campaign and make promises?
