General elections were held in Argentina on 27 October 2019, to elect the president of Argentina, members of the national congress and the governors of most provinces.

The Peronist, left-wing Frente de Todos ticket of Alberto Fernández, former Chief Cabinet, and Cristina Fernández de Kirchner, National Senator and former president, defeated the center-right Juntos por el Cambio ticket of incumbent president Mauricio Macri and conservative Peronist National Senator Miguel Ángel Pichetto, exceeding the threshold to win the presidency in a single round. Macri became the first incumbent president in Argentine history to be defeated in his reelection bid.

Electoral system The election of the president was conducted under the ballotage system, a modified version of the two-round system. A candidate can win the presidency in a single round by either winning 45% of the vote, or if they win 40% of the vote while finishing 10 percentage points ahead of the second-place candidate. If no candidate meets either threshold, a runoff takes place between the top two candidates. Voting is compulsory for citizens between 18 and 70 years old. Suffrage was also extended to 16- and 17-year-olds, though without compulsory voting.Voto de los Jóvenes de 16 y 17 años0 Camara Nacional Electoral

The 130 seats of the Chamber of Deputies up for election were elected from 24 multi-member constituencies based on the 23 provinces and Buenos Aires.

Opinion polls

Results Primary elections

Open primary elections for the presidency were held nationwide on 11 August. With this system, all parties run primary elections on a single ballot. All parties must take part in it, both the parties with internal factions and parties with a single candidate list. Citizens may vote for any candidate of any party, but may only cast a single vote. The most voted candidate of parties gaining 1.5% or higher of the valid votes advances to the general election.

Fernández came top with 47.8% of the vote, with Macri trailing behind with 31.8%. Lavagna, del Caño, Gómez Centurión and Espert all received enough valid votes to participate in the general election.

President

Fernández owed his victory mostly to Buenos Aires Province swinging over dramatically to support him; he carried it by over 1.6 million votes over Macri, accounting for almost all of his nationwide margin of 2.1 million votes. By comparison, Daniel Scioli only carried the province by 219,000 votes in 2015.
