Resumen de How catchall parties compete ideologically: beyond party typologies

Ben Mainwaring, Sean D. McGraw

• The catchall party remains a useful concept despite the lack of a widely agreed definition or list of parties. This article suggests defining catchall parties based on how they act strategically. Although catchall parties act strategically on both the organisational and ideological dimensions, this article concentrates on three key ideological features: catchall parties are ideologically centrist, dispersed and flexible over time. Relying on original surveys in the Republic of Ireland, which interviewed two‐thirds of parliamentarians, it is confirmed that Ireland's ‘catchall’ and ‘programmatic’ parties clearly differ in terms of how they compete ideologically. Ireland's catchall parties employ all three identified strategies. Smaller, more programmatic parties are consistent over time, non‐centrist and extremely ideologically coherent on core programmatic issues. The competition between catchall parties and ideological populist parties is a pressing issue, and the Irish case provides new theoretical insights and empirical evidence to understand these party types.
