Revollo's political career was closely linked to that of her husband, del Granado, who, after achieving the conviction of García Meza, went on to serve in the
Chamber of Deputies before being elected
mayor of La Paz in
1999. Together with del Granado, Revollo was a founding member of the
Fearless Movement (MSM), with which her husband governed the capital for over a decade. Starting from the
2005 elections, the MSM entered an electoral pact with the
Movement for Socialism (MAS-IPSP), through which many of the party's leaders attained elective positions in Congress and the
Constituent Assembly. Among them was Revollo, who in
2006 was elected on the MAS party list to represent
La Paz in the Constituent Assembly. Revollo repeated the victory in
2009 when she was nominated to run for a seat in the Chamber of Deputies. As part of its shared alliance with the MAS, candidacies in the middle and upper-class districts encompassing the city of La Paz were reserved for members of the MSM, a party that enjoyed greater support among the city's urban population. Revollo won handily in circumscription 10, a district del Granado had represented years prior. Once in the Legislative Assembly, the alliance between the MAS and MSM quickly collapsed as a result of the former's decision to contest the
2010 municipal elections alone. From parliament, Revollo took charge of the small group of MSM deputies elected for the 2010–2015 term, establishing a breakaway opposition caucus in the Chamber of Deputies, for which the ruling party sought her removal from office for violating the legislature's anti-defection statutes. Revollo, for her part, challenged the MAS to call a
recall referendum to define whether she and her colleagues should lose their seats. Ultimately, the chamber's Ethics Commission ruled against sanctioning Revollo for political defection on technical grounds. For the duration of her term, Revollo took a pragmatic approach to legislating, supporting the MAS's social project, including making important contributions to legislation in favor of women and the environment, even as she simultaneously criticized the ruling party for its illiberal practices. Although the MSM ran its own slate of candidates for the
2014 general election, Revollo opted not to seek reelection as a parliamentarian. Following the MSM's electoral defeat and subsequent loss of its legal status, both del Granado and Revollo retired from politics, with the latter returning to postgraduate teaching at the Higher University of San Andrés. == Electoral history ==
