Italian Candidates under the Rosato Mixed Electoral System. In Search of Personal Votes in the Plurality Tier?

The Rosato law has established a new electoral system featuring single-member districts (S.M.Ds) along with a prevailing proportional tier. S.M.Ds are typically associated with individual incentives to cultivate a personal vote and with a more direct link between representatives and their local constituency. This article investigates patterns of personalized votes in the Italian elections of March 2018 by analysing voting data about candidates for the Chamber of Deputies who ran in the plurality tier. Results reveal that only a minor – although not negligible – portion of Italian voters cast their ballot for an individual candidate only, and that these votes had almost no impact on the outcomes of competition in S.M.Ds. Moreover, some interesting differences across geographical areas, parties and coalitions emerge in the use of personalized vote.
