Rodriguez was elected Prime Minister in 1985, succeeding the previous conservative Prime Minister Vicente Navarro. Rodriguez was the second democratically elected Prime Minister after the regimes of Alfredo Salva and later Juan Marquez. During Rodriguez's time as Prime Minister, this democracy and stability continued. However, for much of his tenure there were concerns from conservative politicians about some of the socialist policies that Rodriguez's government implemented. Because of this, Rodriguez was ousted by the PSD and replaced by José Manuel Barrera, a centre-left progressive politician, shortly before the General election, 1990.
