List of political parties in Argentina in the context of Argentine National Congress

Mauricio Macri ([mawˈɾisjo ˈmakɾi] ; born 8 February 1959) is an Argentine businessman and politician who served as President of Argentina from 2015 to 2019. He has been the leader of the Republican Proposal (PRO) party since its founding in 2005. He previously served as Chief of Government of Buenos Aires from 2007 to 2015, and was a member of the Chamber of Deputies representing Buenos Aires from 2005 to 2007. Ideologically, he identifies himself as a liberal conservative on the Argentine centre-right.

Born in Tandil, Macri trained as a civil engineer at the Pontifical Catholic University of Argentina and attended Columbia University for business school. After embarking on a business career, he was kidnapped in 1991. The experience prompted him to enter politics, after being released by his captors. He served as president of football club Boca Juniors from 1994 to 2007, reestablishing its profitability which raised his public profile. In 2003 he launched the Commitment for Change, eventually developing it into the modern PRO party. Following an unsuccessful bid for Chief of Government of Buenos Aires in 2003, Macri was elected in 2007 and won re-election in 2011. Four years later he was elected president of Argentina in the 2015 general election – the first presidential runoff ballotage in Argentine history.

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".

General elections were held in Argentina on Sunday, 23 October 2011. Incumbent president Cristina Fernández de Kirchner of the Front for Victory won in a landslide, with 54% of the vote, securing a second term in office. The Front for Victory won just over half of the seats in the National Congress. As of 2023, this marked the last time the vice president-elect was not a woman.

Mercosur Parliamentarians were also popularly elected for the first time. Another novelty was the introduction of open, simultaneous and mandatory primaries. These took place 14 August 2011 to select the candidates of each political party or coalition.
