MIAMI: Like many young voters in Florida, Jared Machado is concerned about rising sea levels, college tuition and landing a job when he graduates from the University of Florida in a few months. But the political science and history major can’t ignore how his father and grandparents came to the United States: as refugees fleeing communist Cuba.

As he considers his options for president in Florida’s March 17 primary, Machado was disappointed and disturbed when US Sen. Bernie Sanders, a self-described democratic socialist, seemed to praise former Cuba dictator Fidel Castro in a recent interview.
