Voting for movement parties in Southern Europe: the role of protest and digital information

Abstract:

In recent years ‘movement parties’ such as Syriza in Greece, the Movimento 5 Stelle in Italy, Podemos in Spain and - to a lesser extent - Bloco de Esquerda in Portugal shook national party systems, breaking the consolidated dynamics of political competition. Despite growing interest in movement parties, there has been scant attention to the role of citizens adopting unconventional forms of action and using digital media in accounting for their electoral performance. To fill this gap, four original internet-based post-electoral surveys are employed showing that protesters and digital media users are more likely to vote for these parties, despite important country differences.
