Typically, the question was simply:

"How do you think we should elect the President: Should it be the candidate who gets the most votes in all 50 states, or the current Electoral College system?"

In state polls of 800 voters each with a second  question that specifically emphasized that their state's electoral votes would be awarded to the winner of the national popular vote in all 50 states, not necessarily their state's winner, there was only a 4-8% decrease of support.

 Question 1: "How do you think we should elect the President: Should it be the candidate who gets the most votes in all 50 states, or the current Electoral College system?"

Question 2: "Do you think it more important that a state's electoral votes be cast for the presidential candidate who receives the most popular votes in that state, or is it more important to guarantee that the candidate who receives the most popular votes in all 50 states becomes president?"
