Protesting with the ballot: Diffusion of methods of electoral protest in Spain

Abstract

This paper shows the pattern of diffusion of a tool of protest – blank and null voting (BNV)– in the context of Spanish national elections. It shows how the 2004 protest mobilization by Batasuna (a Basque nationalist party) predicts null voting by identifying the relationship of this form of protest with both the level of grievance of the population and the political resources of the mobilizers. The paper then demonstrates that this large and visible use of a protest tactic is followed by a heterogeneous diffusion process after the main mobilized protest event and beyond the supporters of the original mobilizer. In the 2008 national election, across Spain, citizens with grievances toward the political system and, most importantly, with political affinity with the initiators were the ones to update their individual protest repertoire with this electoral protest tool.
