In the presidential elections of 2007, Carrió came second, heading the Civic Coalition with Rubén Giustiniani. She obtained about 23% of the vote, coming in a second behind Cristina Fernández de Kirchner. She won the majority vote in two of the three largest cities of Argentina: Buenos Aires and Rosario, but she suffered a larger defeat in Buenos Aires Province, the most populated district, and could not force a run-off election. ARI did however win four Senate seats (2 of the City of Buenos Aires and 2 of Tierra del Fuego) and a considerable number of seats in the Argentine Chamber of Deputies, with further Congress seats for other members of the Coalition.
