After Somoza's win in the December 1936 presidential elections, he proceeded to consolidate his power within the National Guard, while at the same time dividing his political opponents. Family members and close associates were given key positions within the government and the military. The Somoza family also controlled the PLN, which in turn controlled the legislature and judicial system, thus giving Somoza absolute power over every sphere of Nicaraguan politics. Nominal political opposition was allowed as long as it did not threaten the ruling elite. Somoza Garcia's National Guard repressed serious political opposition and antigovernment demonstrations. The institutional power of the National Guard grew in most government owned enterprises, until eventually it controlled the national radio and telegraph networks, the postal and immigration services, health services, the internal revenue service, and the national railroads.
