This article focuses on party system innovation (PSInn), defined as the aggregate level of ‘newness’ recorded in a party system at a given election. After...

The economic crisis, the fall of the Berlusconi government and the birth of the technocratic government led by Mario Monti have produced several changes in the Italian political system. Certainly, one of the most important innovations in the context of Italian politics has been the emergence of the Five Star Movement. Such a new party has achieved spectacular overnight success in several elections at sub-national level, and now it is the most voted party in the 2013 national elections. The Five Star Movement combines antiestablishment rhetoric with demands for political reform. The article analyses the electoral growth of the Five Star Movement using both aggregate data and individual data from “Osservatorio Politico CISE” (i.e. cross-section and panel surveys conducted from November 2011 to March 2013). In particular, the author investigates whether the profile of the supporters of the Five Star Movement has changed over time, both from a political and a social standpoint. Finally, the author analyses what factors influence the electoral choice for the Five Star Movement, also from a longitudinal perspective.

The literature highlights how different individual levels of political interest and knowledge matter for political attitudes and behavior. A logical-quantitative voting model is thus proposed for a two-party system, based on voters' left–right ideological positions and their degree of political involvement. The model hypothesizes that although more involved voters generally behave in accordance with their ideological orientation, those who are less involved do not. Moreover, the latter tend to be more undecided and therefore likely to be more strongly influenced by campaign activities. This model is then applied to survey data regarding the 2001 Italian general elections. Results confirm the hypotheses and show that the most competitive area is ideologically a narrow centrist area for very involved citizens, becoming wider as the level of involvement decreases. Separate analyses are carried out for different geopolitical areas of the country, with results fitting the political history of these areas.
