Luis Arce Catacora was sworn in as Bolivia’s new president last weekend, two weeks after he and his vice president, David Choquehanca Cespedes, won decisively in long-delayed general elections. Their victory marked a return to power for the Movement for Socialism—the political party of former President Evo Morales, known as the MAS—and an end to a year of unrest and political turmoil that followed Morales’ ouster in the wake of disputed elections.
