While most studies concentrate on relatively high levels of commitment to social movements, pervasive weak support has received less attention. Ballot initiatives are one of a class of tactics which translate latent support into concrete influence. Because they are “low cost” mobilizations for individual supporters, such initiatives can minimize free riding, and are ideal for exploring weak support. A social psychological analysis complementary to resource mobilization theory reveals the impact and interactions of voters' social definitions, along with background factors. Levels of grievance, cost, and efficacy, along with demographic and political variables predict support for a recent nuclear free zone campaign.
