Eh, I think this is more clearly about diplomacy than, say, the "well regulated militia" stuff. And still, i the compact is repealed, the states are free to apportion their electors however they like. States could also independently match the popular vote when it wouldn't make a difference. Even such a "dry run" would shake things up. Bottom line, unless there is a different law to require the states to apportion electors a cetain way, I don't really know how to stop it.
