Is the National Popular Vote unconstitutional?
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. The compact is designed to ensure that the candidate who wins the most popular votes is elected president, and it would come into effect only when it would guarantee that outcome. As of February 2019, it has been adopted by eleven states and the District of Columbia. Together, they have 172 electoral votes, which is 32.0% of the Electoral College and 63.7% of the 270 votes needed to give the compact legal force.
By awarding the votes based on who ever gets more nationally this compact would virtually eliminate the electoral college. And allow 6 states to elect the President.
