Bullrich represented the hardest and most right-wing sector of the Together for Change coalition and the Republican Proposal party during both the 2023 Argentine primary and general elections as presidential candidate.

[3] On her father's side, she descends from Adolfo Bullrich, a businessman and politician of German ancestry, who served as Mayor of Buenos Aires from 1898 to 1902.

In the TV program "Almorzando con Mirtha Legrand" Cantilo explained that their mothers were siblings, had a frequent relation, and that Bullrich invited her to a concert of the band Pescado Rabioso, led by Luis Alberto Spinetta.

[8] Patricia skipped school classes one day to attend the music competition TV program "Si lo sabe cante", where she sang the song "El extraño de pelo largo" of La Joven Guardia.

[5] Patricia's grandmother, daughter of Honorio Pueyrredon, took her to meet Ricardo Balbín, leader of the Radical Civic Union (UCR).

Rather than make her embrace the ideas of the UCR, supportive of liberal democracy, she rejected Balbín and chose Peronism instead, which proposed far-left politics at the time.

[9] She was also present at the Plaza de Mayo on the International Workers' Day of 1974, when Perón, who had once again become president of Argentina, expelled the Montoneros and the left-wing youth groups from the celebrations.

[12][13] Perón died in 1974 and the Dirty War, an armed conflict between the Montoneros and the military, worsened: the guerrillas resumed the tactics used years before to attempt to remove the current authorities from power.

In 1975, Bullrich was arrested for spray-painting political messages on the entrance of the University of Buenos Aires Faculty of Philosophy and Letters, and spent six months in prison.

Upon being released, she dropped out of her sociology degree at the University of Buenos Aires and enrolled at the Universidad de Belgrano to study law.

[10] In January 1977, Galimberti and Bullrich attached an improvised explosive device to the car of Pepe Noguer, mayor of San Isidro.

[15] Peronism lost the 1983 Argentine general election, so she joined the internal faction of Antonio Cafiero that sought to renew the party.

[19] De la Rúa resigned, and eventually the governor of Buenos Aires Eduardo Duhalde was appointed president by the Congress.

[20] The UPT did not take part in the elections, supporting instead Ricardo López Murphy of the Recreate for Growth party,[21] who ended in the third place.

[22] The UPT joined forces with the Support for an Egalitarian Republic (ARI) and created the Civic Coalition to run for the 2007 Argentine general election, with Elisa Carrió as a candidate for president.

[23] Her centrist politics and polemical history as a government minister, however, contributed to the disenchantment of a group of left-wing members of ARI who left the Civic Coalition.

[25] Within the first days, three criminals convicted by the triple crime escaped from a high-security prison, leading to a nation-wide operation to recapture them.

The case became a national scandal, with the Gendarmerie being accused of an alleged enforced disappearance, and by extension their political authorities, Bullrich and Macri.

Other politicians briefly considered to run for vice-president under her were Carlos Melconian, Maximiliano Abad, Luis Naidenoff, and Ricardo López Murphy.

Before implementing it, fiscal deficit would be eliminated, the by-laws of the Central Bank would be amended to prohibit money emission, and the restrictions to the use of US dollars would be removed.

Massa made a speech about institutional stability and public security, usual topics of the UCR and PRO respectively, and Milei focused on the need to join forces against Kirchnerism.

The Workers' Party made an habeas corpus request to prevent the protocol from coming into force, which judge Gustavo Pierretti rejected.

[48] The city of Rosario had ongoing problems with narcotrafficking cartels, who had moved beyond the illegal drug trade into other illicit activities, such as extortion and contract killing.

One of the initial actions was to enforce stricter conditions at the local prisons, as several crime bosses were already jailed but managed to control the criminal operations nonetheless.

She started to have doubts over her allegiance to the guerrillas when she found out that Montoneros had killed the priest Carlos Mugica, and the aide of Perón José Ignacio Rucci.

She also considers that this style of government was used by the Kirchners to advance policies that are long outdated in the rest of the world, and to conceal its negative results.

[53] When she was appointed minister of security by Javier Milei, she said "True change is possible if the law is applied in every corner of the country, equally for everyone and without privileges.

[54] However, she also supported a clause for conscientious objection to abortion from medics that may refuse to do it, and to set a minimum age higher than in the proposed bill.

That time, Bullrich refused to comment her personal opinion on abortion, and considered instead that the country had more pressing economic and societal priorities.

[56] For similar reasons, she did not agree with the proposal of Javier Milei to celebrate a referendum to abolish the bill approved in 2020: she said that it would halt the whole country for a couple of months, and that the priority was to solve the economic crisis.
