The Offensive of the Democratic Left (Spanish: Ofensiva de la Izquierda Democrática, OID) was a small reform-oriented centrist political party in Bolivia.
The Offensive of the Democratic Left was founded in 1978 by ex-President and former leader of the Social Democratic Party Luis Adolfo Siles Salinas (half-brother of Nationalist Revolutionary Movement of the Left leader Hernán Siles Zuazo).[1]
In 1978, the Offensive of the Democratic Left took part in an electoral coalition Democratic and Popular Union backing Hernán Siles Zuazo.[2]
For the 1980 elections, the Offensive of the Democratic Left was the component of the Democratic Revolutionary Front-New Alternative, with the OID's leader Luis Adolfo Siles Salinas as the coalition's presidential candidate.[3]
After the coup d'état on 17 July 1980, the Offensive of the Democratic Left disappeared.
