Book Review on Italian Political Science (by Luca Verzichelli, University of Siena)
This volume is an important contribution to the field of comparative political institutions because it focuses on the growing role of party leaders who assume a relevant institutional power in many advanced democracies. The notion of “presidentialization” is at the core of the volume’s theoretical framework. However, in contrast to other pieces of empirical research emphasizing the impact of institutional changes on the development of party structures, the volume endeavors to explore the phenomenon of the increasing importance of party leadership independently from the evolution of the institutional setting. This is, as noted by the editor in the introduction, the “missing link” in the study of presidentialization. More precisely, Passarelli aims to explain the varying intensities of “party presidentialization” one can observe by comparing certain countries using a simplified framework built on two separate dimensions: institutional presidentialization and party genetic presidentialization.
