In Gallup polls since they started asking in 1944 until this election, only about 20% of the public has supported the current system of awarding all of a state's electoral votes to the presidential candidate who receives the most votes in each separate state (not mentioned in the U.S. Constitution, but later enacted by 48 states) (with about 70% opposed and about 10% undecided).

Support for a national popular vote for President has been strong among Republicans, Democrats, and Independent voters, as well as every demographic group in every state surveyed. In the 41 red, blue, and purple states surveyed, overall support has been in the 67-81% range - in rural states, in small states, in Southern and border states, in big states, and in other states polled. 

The National Popular Vote bill is 61% of the way to guaranteeing the majority of Electoral College votes and the presidency to the candidate who receives the most popular votes in the country.
