This article has the purpose to assess if and how party system nationalization affects individual voting behaviour. Previous studies on party system nationalization have focused on systemic processes, exclusively dealing with aggregate data. The authors address this topic from a new empirical perspective, arguing that party system nationalization could act as a context dimension interacting with the vote choice function. How does this specific context dimension moderate the explanatory power of individual level characteristics? On which determinants of vote choice does party system nationalization have a greater impact? To answer these questions, the authors focus on 23 European countries through the use of the 2009 European Election Study. The empirical analysis shows that in nationalized contexts the impact of the left-right dimension on party support is higher than in territorialized contexts, while that of class as well as of culture-related variables is lower. The authors also discuss the implications of these findings.

This article analyzes the results of the Italian municipal elections held in May 2011. First, we make a simple count of the municipalities won by the various political blocs, and secondly we make a comparison with the results of regional elections of 2010. We have compared data concerning both the electoral performances of political blocs and those of the political parties who appeared in this election. We also present the results as disaggregated data, both from a demographic standpoint and from a geographical point of view. The analysis shows a clear electoral defeat of the center-right coalition, both in terms of municipalities lost and in terms of percentages of votes obtained. The fact that these two phenomena have occurred especially in the North, its traditional area of electoral strength, makes this defeat particularly significant. The center-left coalition, due to the difficulties of its opponent, gets a good result in terms of number of municipalities won, while not improving its performance in terms of percentages of votes obtained. The centrist coalition, finally, does not get a great performance in terms of votes obtained, but it often proves decisive in forcing the other two coalitions to the second ballot.
