Answer: Party members joined the Washington Commonwealth Federation and sometimes took leadership roles in the new unions that emerged starting in 1934. Never a mass organization--CP membership in the state rarely exceeded 2,000--the Party nevertheless was uniquely adept at organizing their way into influential positions in unions and coalitions like the WCF and the Washington Pension Union. Important too was their role in promoting civil rights activism in the 1930s.
The left had many dimensions, including a partially revived Socialist Party, a residual but active group of IWWs, and Trotskyists affiliated with what became the Socialist Workers Party in 1938. Unaffiliated radicals outnumbered all of those who followed particular parties and that makes it hard to precisely define and count the 1930s left. Where earlier in the century, the Socialist Party had provided the big umbrella covering much of the left, in the 1930s radicals worked in unions, unemployed organizations, civil rights coalitions, and most of all inside the New Deal Democratic Party.
