He moved, this time to Antofagasta, where he founded "El Socialista" ("The socialist") newspaper. In 1915 he was a candidate for Congress for Antofagasta, but was defeated (probably due to massive fraud). He then moved back to Valparaíso where he lived until 1916, when he started a tour along Chile all the way to Punta Arenas. In 1918 he travelled to Argentina where he participated in the foundation of the Communist Party of Argentina, becoming a member of its first national directory.
