Party Differences and Spatial Representation: The Irish Case

‘The Irish party system is unique. In no other European polity does a small number of programmatically indistinguishable parties, each commanding heterogeneous electoral support, constitute the entire party system.’ This bold statement is merely a particularly forthright expression of a commonly held view about political parties in the Republic of Ireland. This view is understandable given that the formal casus belli between the two major parties was the Anglo-Irish Treaty of 1921; surely this issue must at some stage have been overtaken by events. In the revised edition of his standard text on Irish politics, Chubb points to the year 1948 as the date by which the ‘issues which had split Sinn Fein were either resolved or increasingly irrelevant’. He goes on to argue that from the 1950s ‘all parties were to a great extent drained of ideology; they overlapped considerably in the policies they proposed; and they competed for the votes of a public increasingly concerned with welfare and consumer politics and less and less with national issues’. What we may call ‘the no-differences thesis’ has far-reaching implications for our understanding of the Irish party system and of the role it plays in policy formulation and the wider political process.
