Replication Data for: Dropping off the bandwagon

This paper builds upon established elements of resource mobilisation theory to explain how civil society organisations (CSOs) react to politicisation. Its key theoretical innovation is to foreground the search for organisational maintenance that is an implicit assumption of the resource mobilisation hypothesis. It argues that as politicisation increases, most civil society organizations should be expected to defect from policy bandwagons because they do not have the capacity to offer purposive and solidary incentives to potential supporters. The argument is tested using measures of network centrality from an online forum (Twitter) as a predictor for ongoing participation in campaigns against the Transatlantic Trade and Investment Partnership. The findings show that once the decision to engage in outside lobbying has been made, the need to ensure organizational survival explains ongoing participation better than the increased salience and declining public support which encourages CSOs to get involved in the first place. This is especially evident in European Union member states where they do not have meaningful avenues for political participation. The findings contribute to the literature on politicisation, interest groups and the domestication of European politics.
