Politics of Argentina Political parties Elections

TheSocialist Party (Spanish:Partido Socialista, PS) is acentre-left^[24]political party inArgentina. Founded in 1896, it is one of the oldest still-active parties in Argentina, alongside theRadical Civic Union.^[25]

The party has been an opponent ofKirchnerism andMauricio Macri.^[26][27]

The history ofsocialism in Argentina began in the 1890s, when a group of people, notablyJuan B. Justo, expressed the need for a greater social focus. The PS itself was founded in 1896, led by Justo andNicolás Repetto, thus becoming the firstmass party in the country. The party affiliated itself with theSecond International.^[28] Between 1924 and 1940 it was a member of theLabour and Socialist International.^[29]

Through its life, the party suffered from various splits: the International Socialist Party (which became theCommunist Party of Argentina) and theIndependent Socialist Party were the most notable. The most important of those was in the 1960s, when the party divided itself in half, giving birth to the more radicalArgentine Socialist Party (Partido Socialista Argentino, PSA), and the more moderateDemocratic Socialist Party (Partido Socialista Democrático, PSD). In 1966, two factions departed the PSA:Vanguardia Comunista andPartido Socialista de Vanguardia. In 1972, the remaining of the PSA together with other leftist groups formed thePopular Socialist Party (Partido Socialista Popular, PSP). The PSP and PSD were rejoined in 2002, forming the Socialist Party.

Among the socialist leaders of Argentina, the most remarkable areAlfredo Palacios, who was the first socialist parliamentarian in theAmericas (1904) and aSenator in the 1960s;Juan B. Justo, doctor, philosopher, writer and leader of the party until his death in 1928;Alicia Moreau de Justo (1895–1986), Justo's wife, who was for years the editor of the Socialist newspaperLa Vanguardia;Guillermo Estévez Boero, founder of the Popular Socialist Party; andAlfredo Bravo, a teacher,unionist,human rights militant and respected legislator in the last two decades of the 20th century (died 2003).

The Socialist Party of Argentina maintains an electoral stronghold in the province ofSanta Fe, and particularly inRosario, where mayors have been socialists since 1989. Former two-term mayorHermes Binner slowly became acknowledged as a reference character for the party. In the2005 parliamentary elections a Socialist-Radical alliance led by Binner won 5 seats in the nationalLower House, and in the elections of 2007, Binner, leading a broad, centre-leftist political coalition (theProgressive, Civic and Social Front), became the first Socialist to be elected governor of an Argentine province.^[30]

In the2011 general election, Binner was the Socialist candidate and achieved 2nd place with 16.8% of votes.^[31] Despite this number being well below the 54.1% achieved by Peronist leaderCristina Fernández de Kirchner, the Socialist Party considered the results of the election as significant and a sign of renewed interest by a sector of the population.^[32] In May 2012, Binner became the Socialist Party's president.^[33]

For the2015 general election, the PS entered in coalition with other centre-left and left-wing parties to form theProgresistas (Progressives) front, which endorsedMargarita Stolbizer for the presidency. Stolbizer landed 5th in the election with just over 2.5% of the vote, failing to pass the threshold for the run-off. During the same elections, SocialistMiguel Lifschitz was electedGovernor of Santa Fe, succeedingAntonio Bonfatti (also of the PS).

In April 2016, Bonfatti was chosen to succeed Binner as national president of the party.^[34] Following the2017 legislative election, the party was left with a single national deputy,Luis Contigiani, and no representatives in theSenate. In 2018, Contigiani left the Socialist Party's bloc in the Chamber of Deputies after being criticized by his party for refusing to vote in favor of a bill that would legalizeabortion in the country.^[35][36]

In the2019 general election, PS didn't elect any deputies; however, Socialist politicianEnrique Estévez was elected to the Chamber of Deputies on the list of theProgressive, Civic and Social Front, and thus the Socialist Party regained its representation in the Congress.^[37][38]

In 2021, formerintendente (mayor) ofRosario,Mónica Fein, was elected president of the Socialist Party.^[1]
