Representative Jack Pommer is sponsoring the National Popular Vote bill in the Colorado House of Representatives.

The bill was introduced into Colorado Legislature on January 10, 2007, by Colorado Senate Majority Leader Ken Gordon. The National Popular Vote bill would enact an interstate compact entitled the "Agreement Among the States to Elect the President by National Popular Vote" in Colorado.

In 2006, Colorado's Senate was the first state legislative house in the nation to pass National Popular Vote's legislation for nationwide election of the President (SB 06-223). Among the Senators voting for the bill on its third reading on April 17, 2006, were Senators Ken Gordon (D), John Evans (R), and Lew Entz (R). During debate on April 14, Senate Majority Leader Ken Gordon said,

"We're trying to count every vote equally. … We think the president should be the person who gets the majority vote. It's the bedrock of our democracy."

Senator Evan (Parker) said on April 14,

"This bill addresses some serious flaws in the Electoral College process."

The Colorado Senate's action on April 17, 2006, followed a favorable vote on the bill's second reading on April 14, 2006, and a favorable vote on April 10, 2006, in the Senate Judiciary Committee. At that time, the committee heard testimony from Colorado Common Cause Executive Director Pete Maysmith, National Popular Vote President Barry Fadem, Dr. John R. Koza (originator of the National Popular Vote bill), and Colorado attorney Mark Grueskin. A Denver Post editorial on April 19, 2006, said it is "time to rethink presidential elections."

In a statement on April 15, 2006, referring to the Colorado Senate's favorable vote on the bill's second reading, Senator Gordon said,

"This is the bill that would join Colorado in a compact of states who would all agree to send their votes to the person who receives the largest popular vote in the country. The compact only goes into effect if states representing a majority of the Electoral College join. Right now not everyone's vote is equal in electing a President. I think it makes sense to make the President the person who gets the most votes. It is revolutionary, I admit. It is called democracy. I know some people are concerned. It is a big change, and I don't want to discount the concerns of people who feel we should be cautious, but I believe that if the framers of the Constitution were around now they would favor a woman's right to vote, they would oppose slavery and they would support electing the President by majority vote."
