# 2019 Italian by-elections

The 2019 Italian by-elections were the elections called to fill seats of the Parliament that had become vacant after the 2018 general elections.

## Overview

The new Italian electoral law approved in 2017 and nicknamed Rosatellum, provides the election of members of Parliament in 232 single-member districts for the Chamber of Deputies and in 116 for the Senate of the Republic. Whenever a seat of this kind becomes vacant, a by-election is called, and a new representative is elected.

## Chamber of Deputies
### Sardinia 1: Cagliari

The by-election in the district of Cagliari, Sardinia was held on 20 January 2019, to elect a deputy for the seat left vacant by Andrea Mura, whose resignation was approved by the Chamber of Deputies on 27 September 2018.
The deadline for the presentation of names for the candidacy to the seat was set for 17 December 2018. Four candidates filed papers for running: journalist Andrea Frailis for the Centre-left coalition, Daniela Noli for the Centre-right coalition, councillor and engineer Luca Caschili for the Five Star Movement, and volleyball coach Enrico Balletto for CasaPound.
Noli and Balletto were making a second attempt at election to Parliament after missing out in the 2018 general elections: the former was nominated in second place on her list behind the elected Ugo Cappellacci in the plurinominal district of southern Sardinia, while the latter ran in the single-member district of Cagliari for the Senate of the Republic. Frailis, not affiliated to any party, competed with the support of the new "Progressives of Sardinia" coalition, formation created for the occasion, which unites both the Democratic Party and other formations, such as Free and Equal, that in Parliament formed the previous year two separate groups. Frailis has however announced that in the event of his election he would join the Democratic Party.
The election was characterised by a very low turnout, equal to 15.54%. The two most populous municipalities registered the highest and lowest turnout: Cagliari with 17.17% and Quartu Sant'Elena with 12.46%. Andrea Frailis, the candidate of the centre-left coalition, was elected deputy with 40.40% of the votes, while Daniele Caschili and Daniela Noli stopped respectively at 28.92% and 27.80%. Frailis received maximum votes only in the municipalities of Cagliari, Quartu Sant'Elena and Monserrato, namely the municipalities of the first belt of the city hinterland. These being the most populous municipalities, have determined the victory.
