The
semipresidential voting system was the one used for all mayoral elections in Italy of cities with a population higher than 15,000. Under this system voters express a direct choice for the mayor or an indirect choice voting for the party of the candidate's coalition. If no candidate receives at least 50% of votes, the top two candidates go to a run-off after two weeks. The winning candidate obtains a majority bonus equal to 60% of seats in the City Council. During the first round, if no candidate gets more than 50% of votes but a coalition of lists gets the majority of 50% of votes or if the mayor is elected in the first round but its coalition gets less than 40% of the valid votes, the majority bonus cannot be assigned to the coalition of the winning mayor candidate. The election of the City Council is based on a direct choice for the candidate with a preference vote: the candidate with the majority of the preferences is elected. The number of the seats for each losing party is determined proportionally, using D'Hondt seat allocation. Only coalitions with more than 3% of votes are eligible to get any seats. ==Municipal elections==
