Ascertaining whether local election results are driven by incumbents' performance while in office or mechanically reflect constituencies' ideological affiliation and macroeconomic conditions is crucial for evaluating the alleged accountability-enhancing property of decentralization. On the basis of a unique score of urban environmental performance and the results of all elections held in the major Italian cities over a decade, we investigate the role of local (fiscal and environmental) vs. national issues in municipal elections. Although the empirical evidence points to a strong ideological attachment and a somewhat weaker “fiscal conservatism,” it reveals that media reported environmental rankings have an impact on the popularity of city governments.
