IIRC “interstate compacts” are specifically forbidden by the Constitution unless they're approved by the United States Congress.Although I suspect that there are at least a few such compacts currently operating the only one I know of is the Port Authority of New York and New Jersey...which controls various bridges,tunnels and transit systems as well as three airports in the “tri state” area.

There is also the Delaware River Port Authority in New Jersey and Pennsylvania.

The Uniform Commercial Code is a fifty-state compact in all but name.

Those who think the NPV will be shot down on the basis of being an unauthorized compact will be in for a rude awakening. From precedent, the Scotus LOVES democracy, the popular element to governing. It loves it so much that it elevated the franchise to what it calls a “fundamental right.” The states can allocate their electoral votes as they see fit and no court will stop them.
