Representative Sirota and Representative Arndt, co-prime bill sponsors, presented Senate Bill 19-042. The bill enters Colorado into an agreement to elect the president by national popular vote, which becomes binding on member states once states with the majority of electoral votes ratify the agreement. Under the agreement, presidential electors in Colorado are bound to support the winner of the national popular vote. Any state and the District of Columbia may enter into the agreement. The bill specifies the terms for states to withdraw from the agreement, and the process that must be undertaken by election officials to determine the national popular vote total and certify the national popular vote winner. This agreement terminates if the Electoral College is abolished.
