Small versus Statewide Parties: How Subnational Contestation and Decentralisation Influence Presidential Elections in Europe and Latin America

Abstract

Shugart and Carey were among the first scholars to recognise that there is a relationship between regional and local – or subnational – electoral forces and the presidential race. Yet because of a lack of subnational electoral data, this relationship has largely remained unexplored. We elaborate on Shugart and Carey’s theory to argue that the effects of decentralisation are conditional on a party’s presence in subnational elections for determining when and why parties enter the presidential race. Using an original dataset of subnational electoral results and presidential strategies in 17 countries in Europe and Latin America from 1990 to 2013, we find that parties with a small presence in subnational elections are more likely to compete for the presidency under more extensive decentralisation. Statewide parties, however, contest presidential elections regardless of level of decentralisation. These findings have important implications for understanding Shugart and Carey’s expectation that subnational contestation influences national party systems, presidential elections and democratic representation more generally.
