The EPIC movement spread outside California, especially along the West Coast. In Washington State, the EPIW campaign was ultimately more successful than the California campaign. EPIW elected a number of candidates in 1934, including a US Senator.

The organization adopted the name Commonwealth Builders Inc. when formed in the summer of 1934 as news of Sinclair's electrifying campaign spread north. A weekly newspaper, Washington Commonwealth Builder, appeared on August 23 announcing an End Poverty in Washington program along with a slate of candidates for the upcoming Democratic primary election. When forty-five CBI candidates for local, state, and federal offices won their primary contests in September, it was clear that a new political force had taken shape.

In the November general election, CBI elected a US senator, Lewis Schwellenbach, eight state senators, and twenty-seven state representatives. As in California, the campaign had remade the Democratic Party. Radicals, who for generations had tried to build independent third parties, poured into the party that had until recently been associated with prohibition in the solidly Republican far West. Now the Washington Democratic Party would grow and lean left, pushed by the Commonwealth Builders and successor organizations.

In 1935, the CBI renamed and reorganized itself, becoming the Washington Commonwealth Federation with chapters throughout the state. Representing a broad alliance of radical organizations, unions, and liberal activists the WCF operated as a left-wing caucus within the Democratic Party for the next decade and a half, electing progressive candidates to state and local offices, and sending several to the US Senate and Congress.

With tens of thousands of members, an influential newspaper, and an array of linked organizations, the WCF mobilized progressive Washington State residents into a political caucus that was broadly influential. By the end of the 1930s Washington State had some of the most liberal and comprehensive labor and social legislation thanks to the political power of the WCF.
