Juliana Di Tullio

In the 2017 legislative election, Di Tullio was the first alternate candidate in the Unidad Ciudadana list to the Argentine Senate in Buenos Aires Province; the list was headed by Cristina Fernández de Kirchner and seconded by Jorge Taiana. Unidad Ciudadana came second in the general election, with 37.31% of the vote. In the electoral system for the upper house, this meant that only Fernández de Kirchner was elected as the senator for the minority. Taiana filled the vacancy left by Fernández de Kirchner being elected vice president in the 2019 general election. In 2021, Taiana was sworn in as Defense Minister, and Di Tullio was then tapped to take his seat in the senate for the remainder of the 2017–2023 term. She was sworn in on 19 August 2021.

She ran for a third term in 2013, this time in the second spot in the FPV list, under Martín Insaurralde. During her third term in the Chamber of Deputies, Di Tullio presided the FPV bloc, becoming the first woman to lead a parliamentary caucus in the history of the Argentine Congress. She was also part of the Commerce, Human Rights, Women and Childhood, General Legislation and Foreign Affairs parliamentary commissions.

In 2011, Di Tullio introduced a bill that would expand the right to self-determination for transgender people; the bill was drafted with support from the Federación Argentina de Lesbianas, Gays, Bi y Transexuales (FALGBT). Di Tullio's bill was introduced at the same time as two other similar bill projects were introduced in the Chamber, the other two by Diana Conti (with support from the Comunidad Homosexual Argentina) and by opposition deputies Silvana Giúdici and Miguel Ángel Barrios. The three bills were eventually reformulated into one, which was passed by the Chamber on 30 November 2011.

From 2003 to 2005, Di Tullio was the Argentine foreign ministry's ambassador for women's affairs. At the 2005 legislative election, Di Tullio ran for a seat in the Argentine Chamber of Deputies in the 8th place of the Front for Victory (FPV) list in Buenos Aires Province, and was elected. She ran for re-election in 2009, and although she was not elected, she assumed office upon the resignation of Nacha Guevara from the position. In 2010, she became one of the most vocal supporters of the Equal Marriage bill, which was passed by the Chamber of Deputies on 5 May 2010 and, upon becoming law on 22 July 2010, legalized same-sex marriage in Argentina.

From 2010 to 2011, she was a member of the Parlasur, the legislative body of Mercosur.
