Abstract

The comparative study of intraparty divisions and their determinants has been a long-debated matter, but some issues remain unresolved. First, the problem of the empirical identification of intraparty groups. Second, the lack of comparative perspective and large-N cross-country and cross-time analyses, given intraparty divisions have been studied mostly through theoretical or, at best, small-N analyses. Third, the underestimation of the potential role exerted by contextual factors because of the emphasis put almost exclusively on intraparty dynamics. To fill these gaps, the article employs a measure of visible intraparty fractionalization allowing for large-N cross-time and cross-country comparison. Moreover, by focusing on about 700 party cases in 11 Western European countries since 1965, the article shows that institutional factors, particularly electoral systems’ characteristics, impact intraparty fractionalization. Specifically, intraparty fractionalization is higher in more disproportional systems and where there are stronger incentives for personal vote.

Ha conseguito il dottorato di ricerca in Scienza della Politica presso la Scuola Normale Superiore (ex SUM) di Firenze con una tesi sul processo di nazionalizzazione del voto in Europa occidentale e le sue possibili determinanti. La sua tesi ha vinto il Premio 'Enrico Melchionda' conferita alle tesi di dottorato in Scienze Politiche discusse nel triennio 2012-2014 e il Premio 'Celso Ghini' come miglior tesi di dottorato in materia elettorale del biennio 2013-2014. È membro del CISE, di ITANES (Italian National Election Studies) e co-coordinatore del Research Network in Political Parties, Party Systems and Elections del CES (Council of European Studies). I suoi interessi di ricerca si concentrano sulle elezioni e i sistemi di partito in prospettiva comparata, con particolare riferimento ai processi di nazionalizzazione e istituzionalizzazione. Ha pubblicato articoli su Comparative Political Studies, Party Politics, South European Society and Politics, Government and Opposition, Regional and Federal Studies, Journal of Contemporary European Research, oltre che sulle principali riviste scientifiche italiane. La sua monografia Cleavages, institutions, and competition. Understanding vote nationalization in Western Europe (1965-2015) è edita da Rowman and Littlefield/ECPR Press (2018). Sulle elezioni italiane del 2018, ha curato la Special Issue di Italian Political Science ‘Who’s the winner? An analysis of the 2018 Italian general election’.
