It is also a supporter of single payer at the federal level through Medicare for All as introduced into the US Congress by Pramila Jayapal in the House of Representatives and Bernie Sanders in the Senate.

In 2018 Erin Georgen filed a ballot initiative to the people (I-1600) to establish a statewide single payer healthcare plan called the Whole Washington Health Trust.

In 2021 Whole Washington ran an updated version of I-1600 as an initiative to the legislature (I-1362)[4] but the campaign was suspended in August 2021 due to public health concerns during the spike of the Delta variant of COVID-19.

[5] In 2022, campaign director Andre Stackhouse filed I-1471 on behalf of Whole Washington but the initiative did not ultimately collect enough signatures to make the ballot.

The plan's coverage includes dental, hearing, vision, reproductive care and other healthcare services not covered by traditional Medicare.
