The National Popular Vote compact doesn't go into effect until:

• Enough states sign on to form a minimum of 270 electoral votes;
• Congress approves it, which is a requirement of all interstate pacts.

Then comes a court test as to whether the whole thing violates Article IV/Section 4, in which the federal government guarantees to all states a republican form of government.
