If President Raul Castro runs and is re-elected on 16 April 2016 to a five-year term as First Secretary of the Communist Party of the Republic of Cuba, there may be implications for 2016, 2017 and 2018 legislative initiatives in the United States Congress.
From Wikipedia: "The Communist Party of Cuba (Spanish: Partido Comunista de Cuba, PCC) is the only political party permitted to rule in the Republic of Cuba, although others exist. It is a Communist party of the Marxist-Leninist model. The Cuban constitution ascribes the role of the Party to be the "leading force of society and of the state." As of April 2011, the First Secretary of the Communist Party of Cuba is Raúl Castro, the President of Cuba, younger brother of the previous First Secretary and President of Cuba, Fidel Castro, and the Second Secretary is [85-year-old] José Ramón Machado Ventura."
The Communist Party of the Republic of Cuba will hold its Seventh Congress on 16 April 2016.
President Castro is scheduled to retire on 24 February 2018.
The Libertad Act (Helms-Burton) of 1996 has a provision that requires a government of the Republic of Cuba that does not include either (former president) Fidel Castro or Rail Castro as one of the conditions required for a normalization of the bilateral relationship. If President Castro retires as president, but remains First Secretary of the Communist Party of the Republic of Cuba, then there may be a question as to whether that provision of the Libertad Act would be no longer relevant.
Members of Congress supporting legislation to rescind the Cuban Democracy Act (CDA) of 1992, Libertad Act and Trade Sanctions Reform and Export Enhancement Act (TSREEA) of 2000, are expecting to use the retirement of President Castro and fulfillment of a provision of the Libertad Act as a means to obtain support from Members of Congress who may agree that there needs to be changes to statutes, but do not want to be perceived as "rewarding" the Castro brothers.
