That’s the hook that lets the NPV continue to fester.

However, the Constitution is a collection of many clauses, and while NPV may pass muster with the one you cite, it does not with the compact clause.

To be constitutional, laws must be coherent with the entire Constitution, not just selected parts.

I will only back The Popular Vote if Voter ID is implemented in all 50 States

A computer program will be built that tracks all voter ID registered in all 50 States

Once that is implemented will so agree to a Popular Vote

To be constitutional, laws must be coherent with the entire Constitution, not just selected parts.

Many compacts among the states already exist. Suspending licenses in one for offenses committed in another, etc. Maybe you are wiling to bank on John Roberts drawing a tighter definition, but I'm not.
