Robert Speel explains how to establish a national popular vote in a post for The Conversation: "One way to create a national popular vote election for president without amending the Constitution is a plan called the National Popular Vote Interstate Compact. Created by Stanford University computer science professor John Koza, the idea is to award each state's electoral votes to the winner of the national popular vote instead of the winner of the state popular vote. The proposal has received support in 10 states and the District of Columbia.
