Justicialist Party in the context of 2023 Argentine general election

Néstor Carlos Kirchner ([ˈnestoɾ ˈkaɾlos ˈkiɾʃneɾ] ; 25 February 1950 – 27 October 2010) was an Argentine lawyer and politician who served as the president of Argentina from 2003 to 2007. A member of the Justicialist Party, he previously served as Governor of Santa Cruz Province from 1991 to 2003, and mayor of Río Gallegos from 1987 to 1991. He later served as first gentleman of Argentina during the early tenure of his wife, Cristina Fernández de Kirchner, the first person to serve in this role. Ideologically, he identified himself as a Peronist and a progressive, with his political approach called Kirchnerism.

Born in Río Gallegos, Santa Cruz, Kirchner studied law at the National University of La Plata. He met and married Cristina Fernández at this time, returned with her to Río Gallegos at graduation, and opened a law firm. Commentators have criticized him for a lack of legal activism during the Dirty War, an issue he would involve himself in as president. Kirchner ran for mayor of Río Gallegos in 1987 and for governor of Santa Cruz in 1991. He was reelected governor in 1995 and 1999 due to an amendment of the provincial constitution. Kirchner sided with Buenos Aires provincial governor Eduardo Duhalde against President Carlos Menem.

Peronism, also known as justicialism, is an Argentine ideology and political movement with a populist tendency, based on the ideas, doctrine, and legacy of Juan Perón (1895–1974). It has been an influential movement in 20th- and 21st-century Argentine politics. Since 1946, Peronists have won 10 out of the 14 presidential elections in which they have been allowed to run. Peronism is defined through its three flags: "social justice" (the fight against social and economic inequalities), "economic independence" (an economy that does not depend on other countries, by developing its national industry), and "political sovereignty" (the non-interference of foreign powers in domestic affairs).

Peronism, as an ideology, is described as a social form of nationalism, as it promotes a sense of national pride among Argentines. However, it promotes an inclusive form of nationalism that embraces all ethnicities and races as integral parts of the nation, distinguishing it from racial or chauvinistic ethno-nationalism that prioritizes a single ethnic group. This is due to the ethnically heterogeneous background of Argentina, which is a result of the mixing between indigenous peoples, Criollos, various immigrant groups, and their descendants. Likewise, Peronism is generally considered populist, as it relies on the figure of a leader (originally embodied by Perón) to lead the masses. Consequently, it adopted a third position in the context of the Cold War, as expressed in the phrase: "we are neither Yankees nor Marxists."

Isabel Martínez de Perón (Spanish pronunciation: [isaˈβel maɾˈtines ðe peˈɾon] , born María Estela Martínez Cartas; 4 February 1931) is an Argentine politician who served as the 41st president of Argentina from 1974 to 1976. She was one of the first female republican heads of state in the world, and the first woman to serve as president of a country. Perón was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, she served as both the 29th vice president and first lady of Argentina. From 1974 until her resignation in 1985, she was also the second President of the Justicialist Party. Isabel Perón's politics exemplify right-wing Peronism and Orthodox Peronism. Ideologically, she was considered close to corporate neo-fascism.

Following her husband's death in office in 1974, she served as President for almost two years before the military took over the government with the 1976 coup. Perón was then placed under house arrest for five years before she was exiled to Spain in 1981. After democracy was restored in Argentina in 1983, she was a guest of honor at President Raúl Alfonsín's inauguration. For several years, she was a nominal head of Juan Perón's Justicialist Party and played a constructive role in reconciliation discussion, but has never again played any important political role.

Cristina Elisabet Fernández de Kirchner (née Fernández; born 19 February 1953) is an Argentine lawyer, politician who served as the 56th President of Argentina from 2007 to 2015, and later as the 37th Vice President of Argentina under President Alberto Fernández from 2019 to 2023.

The widow of Néstor Kirchner, she was also First Lady during his presidency from 2003 to 2007. She was the second female president of Argentina (after Isabel Perón) and the first to be directly elected to office. Ideologically self-identified as a Peronist and a progressive, her political approach is called Kirchnerism. Since 2024, she has been the president of the Justicialist Party.

Kirchnerism (Spanish: Kirchnerismo [kiɾʃneˈɾismo]) is an Argentine centre-left to left-wing political movement based on ideals formed by the supporters of spouses Néstor Kirchner and Cristina Fernández de Kirchner, who consecutively served as Presidents of Argentina. Although considered a branch of Peronism, it is opposed by some factions of Peronists and generally considered to fall into the category of left-wing populism. It is considered a representative of the socialism of the 21st century, although similarly to Peronism and in contrast to other left-wing ideologies, it is highly nationalist and populist rather than class-based.

Although originally a section in the Justicialist Party, Kirchnerism later received support from other smaller Argentine political parties (like the Communist Party or the Humanist Party) and from factions of some traditional parties (like the Radical Civic Union and the Socialist Party). In parties which are divided along Kirchnerist and anti-Kirchnerist lines, the members of the Kirchnerist faction are often distinguished with the letter K (for instance "peronistas K", "justicialistas K", "radicales K", or "socialistas K") while the anti-Kirchnerist factions, those opposing Kirchnerism, are similarly labelled with the expression "anti-K".

Carlos Saúl Menem (Spanish pronunciation: [ˈkaɾlos ˈmenen] ; 2 July 1930 – 14 February 2021) was an Argentine politician who served as the president of Argentina for ten years, from 1989 to 1999. He identified as Peronist, serving as President of the Justicialist Party for 13 years (from 1990 to 2001 and again from 2001 to 2003), and his political approach became known as Menemism.

Born in Anillaco, La Rioja, to a Syrian family, Menem was raised as a Muslim, but later converted to Roman Catholicism to pursue a political career. Menem became a Peronist during a visit to Buenos Aires. He was elected governor of La Rioja in 1973, deposed and detained following the 1976 Argentine coup d'état, and re-elected in 1983. He defeated the Buenos Aires governor Antonio Cafiero in the primary elections for the 1989 presidential elections. Hyperinflation and riots forced outgoing president Raúl Alfonsín to resign early, shortening the presidential transition.

General elections were held in Argentina on 25 October 2015 to elect the President and National Congress, and followed primary elections which were held on 9 August 2015. A second round of voting between the two leading candidates took place on 22 November, after surprisingly close results forced a runoff. On the first runoff voting ever held for an Argentine Presidential Election, Buenos Aires Mayor Mauricio Macri narrowly defeated Front for Victory candidate and Buenos Aires Province Governor Daniel Scioli with 51% of the vote. Macri's vote count of nearly 13 million votes made it the highest number of votes any candidate has ever received in Argentinian history until Javier Milei's victory in the 2023 presidential election. He took office on 10 December, making him the first freely elected president in almost a century who was not either a Radical or a Peronist.

Macri performed better among higher-income provinces in the central area of the country, while Scioli performed strongly in poorer provinces in the northwest, the northeast and Patagonia.
