Quiroga ran for president in his own right in the
2005 election, as the candidate for a new right-of-center coalition known as
Social and Democratic Power (PODEMOS), which included the bulk of Banzer's former ADN organization. His main opponent was the leftist
Evo Morales of the
Movement Towards Socialism. Morales won the election and Quiroga finished a distant second place, receiving 28.6% of the vote. He has also worked as a consultant for the
World Bank and the
International Monetary Fund. In 2002, he was honored in a tribute exhibit at his alma mater, Texas A&M University. He is, as of November 2016, active in the private sector and many international organizations, among them: as vice-president of Club de Madrid with almost 100 former heads of state and government; on the board of Results for Development-R4D in Washington D.C.; as a member of the
Inter-American Dialogue and the International Advisory Council of the China Economic Club; and in different capacities on the Global Adaptation Institute, the Foro Iberoamericano and many others. He has presided FUNDEMOS since 2002, a Bolivian public policy foundation. His areas of expertise are: management of international aid and cooperation for developing countries; macroeconomic policy; constitutional, legal and institutional reforms; private and official external
debt restructuring and relief; programs to reduce drug trafficking and cocaine production; and broadly in South American public policy, trade, economics, finance and banking, integration, politics and development issues. He was appointed as vice president of the
Club de Madrid in 2011. On 2 December 2019, the interim government of
Jeanine Áñez appointed Quiroga as an international delegate on a special mission to denounce alleged
human rights violations by the ousted Morales administration. He held the post for just over a month, before resigning on 8 January 2020 in order to announce his presidential candidacy for the
snap elections to be held later that year. Throughout the election cycle, he remained around sixth place reaching between 1 and 2% in
opinion polling and never surpassing 7%. On 11 October, one week before the scheduled election, Quiroga announced he was dropping out of the presidential race. He indicated in his withdrawal announcement that he wished to prevent an outright victory of
Luis Arce of the
Movement for Socialism party in the first electoral round by consolidating the right around
Carlos Mesa. He previously served as a senior advisor at
New Direction, a think tank affiliated with the
European Conservatives and Reformists Party in the European Parliament, until 2023. He supported
Javier Milei in the
2023 Argentine general election. For the
2025 elections, he announced his presidential candidacy with the
electoral alliance Libertad y Democracia ("Freedom and Democracy"), abbreviated as
Libre: a coalition formed by the
Frente Revolucionario de Izquierda (
Revolutionary Left Front) and the
Movimiento Demócrata Social (
Social Democratic Movement), with
Juan Pablo Velasco as his running mate for vice president. After receiving around 26% of the votes in the first round on 17 August 2025, == Electoral history ==
