Vidal was born in Buenos Aires. She was raised in the Flores ward and enrolled in the Pontifical Catholic University of Argentina, earning a degree in Political Science. She met Ramiro Tagliaferro, a classmate at the university, and they married in 1998; the couple has a son and two daughters. She began her career in Grupo Sophia, a think tank founded by Horacio Rodríguez Larreta. She was named director of the group's social policy desk in 2000, as well as of Fundación Creer y Crecer, a think tank organized by Commitment to Change, a conservativepolitical party led by mayoral candidate Mauricio Macri. She is also a member of Washington D.C. based think tank, The Inter-American Dialogue. Vidal was elected to the Buenos Aires City Legislature in 2003, and was appointed Chair of the Committee on Women and Youth. She served in the Human Resources Department at PAMI, and as adviser to ANSES, as well as the nation's Ministries of Social Development and Foreign Relations. Vidal was fielded in the Republican Proposal party list as a candidate for a seat in the Argentine Chamber of Deputies for Buenos Aires Province in 2005, though unsuccessfully; she was later elected to the Buenos Aires City Legislature. The election of PRO leader Mauricio Macri as Mayor of Buenos Aires in 2007 led to Vidal's nomination as the city's Minister of Social Development. She requested maternity leave from the post ahead of her scheduled December 10 swearing-in for the birth of her third child, and took office on May 27, 2008. Vidal's profile rose following the 2009 election of Deputy Mayor Gabriela Michetti to a seat in the Chamber of Deputies, and she became Mayor Macri's most visible female adviser. Following Macri's decision to forfeit a PRO candidacy for the 2011 presidential election, and instead seek a second term as mayor, he nominated Vidal as his running mate. The duo were reelected by a landslide on July 31, 2011, receiving over 64% of the vote with sociologistDaniel Filmus coming in 2nd place. Macri selected Vidal as the candidate of his party to run for governor of the Buenos Aires Province in the 2015 elections. The Radical Civic Union, allied with PRO in the coalition Cambiemos, proposed to replace her with Ángel Posse, but Macri kept Vidal. In another negotiation it was proposed that Sergio Massa resigned as candidate to the presidency and ran for governor in Macri's ticket, but Macri kept Vidal as candidate again. She was the first female governor of the province, and it is the first time in 28 years that a non-Peronist candidate has won the election in the country's most populous province.

On December 10, 2015, she swore before the Buenos Aires Legislature. Shortly after assuming as governor, she announced that she would live together with her husband, Ramiro Tagliaferro, in a special residence within the perimeter of the Morónmilitary air base.
