Unlike other states, California retained a large proportion of the child care centers that had been established during World War II. In 1946, the California state government allocated state funds for child care in response to a vigorous child care campaign. The campaign, which was, in large part, a working mothers movement, was a “transformed maternalist” movement. It used maternalist rhetoric to defend state-subsidized child care that was criticized by more traditional maternalists. Using resource mobilization theory, I explain the relatively (...) high degree of political mobilization on the child care issue in California in terms of the greater availability of co-optable social resources, which California's relatively large wartime child care program provided, and the existence of movement entrepreneurs willing to mobilize these latent resources. Child care advocates were successful because they operated within a relatively favorable political opportunity structure since they did not have to contend with a strained state treasury or a mobilized countermovement and were able to garner the support of a wide variety of women's and social organizations and an influential social reformer.
