Book review: Preferential Voting Systems: influence on intra-party competition and voting behaviour by Gianluca Passarelli

In Preferential Voting Systems: Influence on Intra-Party Competition and Voting Behaviour, Gianluca Passarelli offers a new study of the impact of preferential voting on intra-party competition, facilitated by an extensive number of case studies drawn from nineteen countries. This is an important contribution to the literature on electoral systems, filling a particular gap on preferential voting, writes Gary Wilson, and will also appeal to those with an interest in electoral reform.
