Alongside her husband, Enrique Spinetta, Bernazza founded the Lugar del Sol Foundation for homeless children. The foundation forms part of the Movimiento Nacional Chicos del Pueblo. In 2001, she was appointed Executive Secretary of the Provincial Public Administration Institute (IPAP), later serving as its president from 2004. Simultaneously, from 2006 to 2007, she was president of the Provincial Council for Women in
Buenos Aires Province. In the
2005 legislative election, Bernazza ran for a seat in the
Argentine Chamber of Deputies in the
Front for Victory list in
Buenos Aires; the list received 43.04% of the popular vote, not enough for Bernazza to be elected. She took office on 19 September 2007, however, in replacement of Graciela Rosso, who was elected
intendente (mayor) of
Luján. During this first term, Bernazza introduced a bill to create a national park in
General Lavalle Partido; the bill passed both chambers of Congress, effectively creating the
Campos del Tuyú National Park, the first national park in Buenos Aires Province. Bernazza ran for the Chamber of Deputies again in the
2017 legislative election as the 19th candidate in the
Unidad Ciudadana list in
Buenos Aires Province. The list received 36.28% of the vote, again, not enough for Bernazza to be elected. She would take office in 2020 in replacement of
Daniel Scioli, who was appointed ambassador of Argentina in Brazil. During her second term as national deputy, Bernazza formed part of the parliamentary commissions on Families and Childhood, Science and Technology, Communications, Modernization of Parliamentary Procedure, Maritime Interests, and the bicameral commission on children's rights. She was a supporter of the 2020
Voluntary Interruption of Pregnancy bill, which
legalized abortion in Argentina. ==References==
