Carlos Andrés Pérez Rodríguez (27 October 1922 - 25 December 2010), also known as CAP, was a Colombian politician, best known for serving as the Chairman of the Social Party from 1970-1978 and as President of Colombia from 1978 to 1983. CAP was enormously popular for engineering the Social Party's massive gains in the 1974 election, which brought them control of both the Senate and Chamber of Representatives in Congress for the first time since the 1940's and delivered them the Presidency on the second ballot. In 1978, he was the clear successor to President Betancourt, and won a wide victory on the second ballot after barely missing a majority in the first round.
