...the inter-state compact which requires a bunch of states to put all their electoral votes in the pile for the popular vote winner That's called The National Popular Vote Interstate Compact  Under National Popular Vote, states that combine for at least 270 electoral votes agree to award their electors to the presidential candidate who wins the most individual votes across the nation. (Fifteen states and the District of Columbia, totaling 196 electoral votes, have already passed the measure.) In the 18 states currently without faithless elector laws, the National Popular Vote Interstate Compact would operate in a manner identical to the system that they have been using for over 200 years. In these states (which currently use the state-by-state winner-take-all method of awarding electoral votes), the presidential electors are chosen by the political party whose presidential candidate receives the most popular votes inside the state, and there are no additional requirements placed upon the elector. The National Popular Vote Interstate Compact would operate in the same way, except that the presidential electors would be persons chosen by the political party whose presidential candidate receives the most popular votes across all 50 states and the District of Columbia.  https://www.brookings.edu/blog/fixgov/2020/07/14/supreme-courts-faithless-electors-decision-validates-case-for-the-national-popular-vote-interstate-compact/
