Are Politics Local? An Analysis of Voting Patterns in 23 Democracies

This article measures, compares, and analyzes the degree to which local factors, be they candi-date qualities or district characteristics, affect electoral politics. It applies Morgenstern and Potthoff’s components-of-variance model to 56 parties or coalitions to measure the “local vote” and shows that only in some cases do local factors manifest themselves in voting patterns. To explain this finding, the authors argue that the type of executive system, ideological cohesion, and a country’s ethnic heterogeneity combined with federalism are all strongly tied to the local vote patterns. Statistical tests also show that in spite of the large literature on the incentives that electoral systems can offer to candidates to pursue a personal vote, the electoral system does not have a clear impact on the local vote
