At the same Family Day, she announced that she was pregnant; her daughter Ginevra was born on 16 September.[31] In the 2016 Rome municipal election, she ran for mayor with the support of Us with Salvini, a political party led by Matteo Salvini, and in opposition to the candidate supported by Berlusconi's Forza Italia (FI). Meloni won 20.6% of the vote, almost twice that of FI's candidate, but she did not qualify for the run-off, while FdI obtained 12.3% of the vote.[32] During the 2016 Italian constitutional referendum on the reform promoted by Renzi's government, Meloni founded the "No, Thanks" committee and participated in numerous television debates, including one against the then prime minister Matteo Renzi.[33] As "No" won with almost 60% of the votes, Meloni called for snap elections. When Renzi resigned, she withheld confidence from the next government led by Paolo Gentiloni.[34][35] The 2–3 December 2017 congress of FdI in Trieste saw the re-election of Meloni as president of the party, as well as a renewal of the party logo and the joining of Daniela Santanchè, a long-time right-wing politician.[36]
