Union for the Homeland

In the run-up to the 2019 presidential election, the Kirchnerist faction of the Justicialist Party arranged for the establishment of a common Peronist electoral front. This project ultimately materialized with the formation of the Frente de Todos coalition, which comprised the Justicialist majority along with a number of other parties of the political left and centre. This alliance was itself a successor to both the short-lived Citizen's Unity bloc formed for the 2017 midterm elections as well as the Front for Victory, which served as the political instrument of the Kirchnerist political camp between 2003 and 2017. The alliance presented Alberto Fernández as its sole candidate in the 2019 presidential primaries, in which he secured just under 48% of the vote. In the subsequent general election, Fernández again garnered 48% of the vote, against the 40% of incumbent president Mauricio Macri of the Juntos por el Cambio coalition, ousting the sitting administration and returning the Peronists to power after four years in the opposition.[8] Fernández, along with his vice president, the former President of Argentina Cristina Fernández de Kirchner, went on to govern the country for the ensuing four-year period. Halfway through this term, the Frente de Todos coalition suffered a significant defeat in the 2021 Argentine legislative election, losing seats in both the Chamber of Deputies and the Senate, and thereby losing control of Congress for the first time in nearly 40 years.[9]

In April 2023, President Alberto Fernandez announced that he would not seek re-election in the next presidential election.[10] In the primary elections on August of that year, Sergio Massa defeated Juan Grabois by a margin of nearly 16 percentage points, although it became the worst result for a ruling Peronist coalition since the PASO was first implemented in 2009.[7]
