Speculation is mounting about who, if anyone, might replace Cuban President Miguel Díaz-Canel as U.S. President Donald Trump pushes for change in Cuba’s leadership. Diaz-Canel was Raúl Castro’s handpicked largely figurehead successor in 2018 and the only leader without the last name Castro to govern since the 1959 revolution. He still has two years left in his term —- but some experts and a growing number of Cubans doubt he’ll make it. Experts say two Castro cousins have come into focus as potential replacements. They are Oscar Pérez-Oliva Fraga, Cuba’s deputy prime minister and Raúl Castro’s 55-year-old great nephew, and Raúl Guillermo Rodríguez Castro, Raúl Castro’s grandson, who has never held a government position.
