Italy stands out among advanced industrialized democracies because of its frequency of major electoral reforms. In the postwar period, Italy has experienced four major electoral systems: the proportional representation (PR) system of the First Republic (1948–1992), mixed-member majoritarian (MMM, 1993–2005), and two varieties of PR with majority bonus (2005–2015, 2015–). In addition, there have been many failed attempts at electoral reform through legislation or referendum.

This book examines the effects of preferential voting on intraparty electoral competition and voting behavior. Using data covering 19 countries and over 200 elections, this study sheds light on a somewhat neglected aspect of electoral systems. The author demonstrates that the ability of voters to influence the selection and deselection of MPs under preferential voting systems is not as important as is often assumed. Instead, their ability to shape the election of a given candidate depends heavily on the balance between party power and voter power.
