Analysis of electoral results implies in many cases differences and similarities between various areas of a polity. Differentiated electoral outcomes are evident not only within each context, but also between two (or more) territorial levels, such as elections at national, regional and provincial level, etc. Nevertheless, studying the territorial electoral discontinuities almost inevitably induces the concept of nationalisation of politics. This article presents a comparison between national and sub-national levels expressed in different electoral results between legislative and regional elections in Italy. In order to carry out a consistent analysis, the comparison of vote percentages is made by always referring to a set of seven (families of) parties, obviously modifying the choice of single parties when the offering changed, but keeping the same format for each pair of elections analysed together. The diachronic comparison over a politically relevant time span – as well as analysis at the level of geopolitical areas – gives us a useful framework rich in information. In Italy electoral behaviour in regional and national elections continues to show, albeit gradually and with some vacillations, a marked differentiation.
