The party was for a long time allied with Peronism in elections.

The party was part of the FrePaSo coalition from the 1990s and entered government in 1999 as part of the Alianza between FrePaSo and the Radical Civic Union that brought Fernando de la Rúa to the presidency.

In 2007, the Party backed the Front for Victory and Cristina Fernández de Kirchner as candidate for President of Argentina.

The party was part of the Frente de Todos coalition that supported presidential candidate Alberto Fernández during the 2019 Argentine general election until its dissolution in 2023.

It is now part of the Unión por la Patria coalition, formed in 2023 to support Sergio Massa's presidential campaign.
