The Party System
This chapter focuses on the attributes and development of the Irish party system, describing its structure and where it sits in comparative perspective. As well as examining party size and ideology, the chapter applies Peter Mair’s conceptualization of the party system as the structure of competition for control of the executive to the Irish case. In doing so, it explores the relationship between electoral change and party system change, arguing that the systemic changes that have been emerging since the 2011 election are an extension of a longer-term trend in the opening up of the Irish party system. This incremental change was accelerated by the economic crisis that began in 2008 and its aftermath. The chapter suggests that the Irish party system is potentially at a critical juncture: a moment of uncertainty that provides opportunities for agency (by voters, party leaders, and others) to shape a durable future path.
