The National Popular Vote Interstate Compact (NPVIC) is an agreement among several U.S. states and the District of Columbia to award all their respective 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 will come into effect only when it will guarantee that outcome.[2][3] As of 2016, it has been joined by ten states and the District of Columbia; their 165 combined electoral votes amount to 30.7% of the total Electoral College vote, and 61.1% of the 270 votes needed for it to have legal force.
