IRVWA (now RCVWA) was formed in 2004 to promote Initiative 318 and to advocate for the implementation of Instant Runoff Voting in Washington statewide and locally.

In 2006 IRVWA helped the successful IRV campaign in Pierce County. The first IRV race in Washington State was run in November 2008 in Pierce County. Congratulations to the citizens of Pierce County.

In 2009-10 RCVWA focused on encouraging the adoption of IRV in King County by the Charter Review Commission and an IRV Local Option Bill in the Washington State Legislature.
