In 2006, the computer science professor John Koza wrote a book called "Every Vote Equal". The book argues for a National Popular Vote agreement between states. (Koza knew about agreements between states from his work on lottery tickets.) Koza, Barry Fadem, and others made a non-profit organization called National Popular Vote. This organization promotes the NPVIC. It is led by people from both major political parties, including former Senators Jake Garn, Birch Bayh, and David Durenberger, and former Representatives John Anderson, John Buchanan, and Tom Campbell.
