Abstract: | Proceeding from mass society theory and the theory of social capital, this article discusses the effect of social isolation, social trust, and membership in voluntary organizations on radical right-wing voting in Belgium, Denmark, France, Norway, and Switzerland. By using data from the first and third rounds of the European Social Survey, a number of logistic regression models are estimated. The results indicate that social isolation and social capital, measured as active membership in voluntary organizations, are of marginal value for explaining radical right-wing voting, although there is some cross-national variation. Moreover, the results show that not even members of humanitarian aid and human rights organizations are less likely to vote for the radical right, which clearly questions the universalistic ambitions of Putnam's theory of social capital and its core idea that organizational membership fosters tolerance and civic virtues. |
