 Mesa presidency

In the June 2002 national elections, former President Gonzalo Sánchez de Lozada (MNR) placed first with 22.5% of the vote, followed by coca-advocate and native peasant-leader Evo Morales (Movement Toward Socialism, MAS) with 20.9%. A July agreement between the MNR and the fourth-place MIR, which had again been led in the election by former President Jaime Paz Zamora, virtually ensured the election of Sánchez de Lozada in the congressional run-off, and on 6 August he was sworn in for the second time. The MNR platform featured three overarching objectives: economic reactivation (and job creation), anti-corruption, and social inclusion.

In 2003, the Bolivian gas conflict broke out. On 12 October 2003, the government imposed martial law in El Alto after 16 people were shot by the police and several dozen wounded in violent clashes. Faced with the option of resigning or more bloodshed, Sánchez de Lozada offered his resignation in a letter to an emergency session of Congress. After his resignation was accepted and his vice president, Carlos Mesa, invested, he left on a commercially scheduled flight for the United States.

The country's internal situation became unfavorable for such political action on the international stage. After a resurgence of gas protests in 2005, Carlos Mesa attempted to resign in January 2005, but his offer was refused by Congress. On 22 March 2005, after weeks of new street protests from organizations accusing Mesa of bowing to U.S. corporate interests, Mesa again offered his resignation to Congress, which was accepted on 10 June. The chief justice of the Supreme Court, Eduardo Rodríguez, was sworn as interim president to succeed the outgoing Carlos Mesa.
