It violates the compacts clause.

I don't see it.

"No State shall, without the Consent of Congress, lay any duty of Tonnage, keep Troops, or Ships of War in time of Peace, enter into any Agreement or Compact with another State, or with a foreign Power, or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay."

Is the Uniform Commercial Code unconstitutional?

without the consent of Congress is the key clause here.

This is an illegal compact among several states unless Congress approves. The people pushing this idea say it will kick in when enough states for a majority of electors agree to the compact. But they can not do that without Congress approving.

It's certainly Constitutional for the states to award their electors however they like. But it is not for the states to enter into an illegal compact.
