Divided We Fall: Opposition Fragmentation and the Electoral Fortunes of Governing Parties

This article introduces the concept of opposition fragmentation into the study of the determinants of election results. Empirical studies have demonstrated that anti-government economic voting is likely to take place where the clarity of responsibility (the degree to which voters can attribute policy responsibility to the government) is high. This argument is extended by focusing on the effects of the degree of opposition fragmentation in influencing the extent to which poor economic performance decreases the government's vote share. With data from seventeen parliamentary democracies, it is shown that when there are fewer opposition parties, the relationship between economic performance and governing parties' electoral fortune is stronger. Opposition fragmentation appears to be as strong a factor as the clarity of responsibility.
