Upon returning to Colombia, she was elected councilwoman for the Municipality of Guacarí, and in 1992 she became Mayor of Guacarí post which she occupied until 1994.
In 1996, she married former Senator Julio César Caicedo Zamorano in a religious ceremony officiated in the San Juan Bautista de Guacarí church,[2] that same year she was named Secretary of Health for the Department of Valle del Cauca. Toro inherited the political support once held by the former liberal party leader in Valle del Cauca Carlos Abadía who was jailed as part of the 8000 process scandal, in which members of the Cali Cartel financed the political campaigns of numerous politicians including the presidential campaign of Ernesto Samper who resulted elected.
Because of her support for President Álvaro Uribe Vélez and his bid for re-election, Toro was sanctioned by the Liberal Party in 2004, which prompted to join a splinter group of Congresspersons from different parties who joined to form the Social National Unity Party and backed President Uribe.
During the inauguration ceremony of President Uribe for his second term, as president of the Congress of Colombia, she became the first woman to ever administer the oath of office to the President of Colombia.[4] There was a controversy however, Toro made a mistake and placed the presidential band backwards, with the Colombian flag colors inverted. When Toro was interviewed about this, she explained that "it was to bring good fortune to the new government... ...because you are supposed to wear your panties inverted for good luck".[5]
