National Popular Vote Interstate Compact participant Colorado
Prospects
Political analyst Nate Silver noted in 2014 that all jurisdictions that had adopted the compact at that time were blue states (all of the states who have joined the compact then and since have given all of their electoral college votes to the Democratic candidate in every Presidential election since the compact's inception), and that there were not enough electoral votes from the remaining blue states to achieve the required majority. He concluded that, as swing states were unlikely to support a compact that reduces their influence, the compact could not succeed without adoption by some red states as well. Republican-led chambers have adopted the measure in New York (2011), Oklahoma (2014), and Arizona (2016), and the measure has been unanimously approved by Republican-led committees in Georgia and Missouri, prior to the 2016 election.On March 15, 2019, Colorado became the most "purple" state to join the compact, though no Republican legislators supported the bill and Colorado had a state government trifecta under Democrats. It was later submitted to a referendum, approved by 52% of voters.
In April 2021, reapportionment following the 2020 census caused NPVIC members California, Illinois and New York to each lose one electoral vote, and Colorado and Oregon to each gain one, causing the total electoral votes represented by members to fall from 196 to 195.
