From the Document: "On October 18, 2020, Luis Arce and the leftist Movement Toward Socialism (MAS) party won Bolivia's presidential and legislative elections in a landslide. Arce, former finance minister in the government of President Evo Morales (2005-2019), secured a first-round victory with 54% of the vote. Held nearly one year after Morales's November 2019 resignation following annulled October 2019 elections that were marred by allegations of fraud, the 2020 elections demonstrated voters' continued support for the MAS. U.S. officials congratulated Arce on his victory. U.S.-Bolivian relations could be challenging, given tension in relations under Morales and the Trump Administration's strong support for the conservative interim government."
