The National Popular Vote Interstate Compact (NPVIC) is an agreement among a group of U.S. states and the District of Columbia to award all their electoral votes to whichever presidential candidate wins the overall popular vote in the 50 states and the District of Columbia.
Supporters believe the compact is legal under Article II of the U.S. Constitution, which establishes the plenary power of the states to appoint their electors in any manner they see fit: “Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress”.
But their Compact may run into a problem because they are not allowed to have a Compact:
Article I, Section 10 of the United States Constitution provides that “No State shall, without the Consent of Congress... enter into any Agreement or Compact with another State.”
Good information. Thanks for posting it CCguy!
