The belief system of the Italian Democratic Party: before, during, and after Renzi

This article aims to explore why the 'demolition' of values promoted by Matteo Renzi had profoundly different effects on the factions within the Partito Democratico (Democratic Party, PD). While several studies have examined the PD's political culture, few have investigated the changing attitudes of its factions. We help fill this gap in the literature by analysing the PD's intraparty divisions on the main dimensions of party competition in the new millennium. We draw inspiration from the theory of party change, arguing that changes in a party's dominant coalition craft a new party image. Based on a unique dataset from PD delegates to national assemblies, this article offers new empirical evidence on intraparty cohesion. Our multivariate analysis offers fresh evidence that under Renzi intraparty divisions on economic issues widened, while cohesion on ethical issues increased. Our work indicates that opening the black box of party politics sheds light on new party images.
