The next mayor of Buenos Aires will be decided on July 31 after no candidate secured an outright majority during Sunday’s vote in the Argentine capital. Mayor Mauricio Macri—the frontrunner and leader of the Propuesta Republicana (PRO) party—won 47.1 percent of the vote while Daniel Filmus of the Peronist Frente para la Victoria (FPV) party received 27.8 percent of ballots cast, according to results posted with 79 percent of the ballots counted. Fernando ‘Pino’ Solanas from Proyecto Sur received nearly 13 percent of the votes.

Macri reacted with euphoria: “This was greater than what we imagined. I am happy.” Filmus called on other parties to join him in July. “I’ve heard a lot of coincidences. A lot of forces talking about a fairer Buenos Aires. Those forces need to join me in a common project,” he said.

The July 31 runoff election will serve as a thermometer of the political environment preceding the presidential election on October 23, when President Cristina Fernández de Kirchner (FPV) will run for re-election. Macri himself previously pulled out of the presidential election to focus on the city; he campaigned on a project of inclusion.

President Fernández de Kirchner called Filmus yesterday evening and told him to “fight the battle.” However, only her ministers attended Filmus’ press conference yesterday.
