[11] Macri re-opened Argentina to international markets by lifting currency controls, restructuring sovereign debt, and pressing free-market solutions.

[12][13] PRO began as an alliance between Commitment to Change (CPC) of Mauricio Macri, and Recreate for Growth (Recrear) of Ricardo López Murphy created in 2005.

Macri and López Murphy spoke with Governor Jorge Sobisch, leader of the Neuquino People's Movement, but did not reach an alliance.

Mauricio Macri formed an electoral alliance called Union-PRO with Francisco de Narváez, who was the candidate for Governor of Buenos Aires.

For the 2009 legislative elections, De Narváez and Felipe Solá were the main candidates for national deputies for the Buenos Aires Province and defeated Nestor Kirchner.

María Eugenia Vidal (PRO) defeated Aníbal Fernández and became Governor of the Buenos Aires Province, putting an end to 28 years of Peronist control.

[21][22] In the legislative elections of 2017, Esteban Bullrich, member of Republican Proposal, obtained the first place and Cambiemos defeated the Citizen's Unity of the former Cristina Fernandez de Kirchner.

In June 2019, an extension of the Cambiemos alliance was made: it is renamed Juntos por el Cambio, by adding to Federal Peronism led by Miguel Ángel Pichetto, who would share the presidential formula of space together with Mauricio Macri.

In the province of Buenos Aires, Governor María Eugenia Vidal sought re-election but was defeated by the candidate of the Frente de Todos, Axel Kicillof, who won 52% of the votes against 38% obtained by JxC.

[25] In the city of Buenos Aires, Mayor Horacio Rodríguez Larreta joins the Radical Civic Union and the Socialist Party to the district alliance and is reelected as Chief of Government with 56% of the votes in the first round.

[26] Initially, Javier Milei invited Patricia Bullrich to run in a internal election in a brand new party that would define the candidate.

Bullrich wants PRO to formally join LLA and create a stronger party, while Macri prefers to stay as an autonomous ally.

[39] Despite its heterogeneity and post-ideological profile, PRO can be classified as a centre-right[40][41][42][43] party close to the liberal-conservative tradition and the neoliberal paradigm.

[64][65][66] During Macri's presidency, he liberalized foreign exchange and exports and imports controls, cut some taxes and energy subsidies.

[71] Macri improved the relations with the United States and from Mercosur achieved a free trade agreement with the European Union and closer ties with the Pacific Alliance.

[72][73][74] PRO and Cambiemos opposes strongly the regime of Nicolás Maduro in Venezuela for human rights abuses and calls for a restoration of democracy in the country.

The objective of the foundation was to design public policies and coordinate technical teams for a future national government of Mauricio Macri.
