Dirty Tricks in Miami-Dade as Diaz-Balarts Fight for Seats

John McCain supports the 48-year old US embargo on Cuba; Barack Obama has said he'd be open to diplomacy, even if Fidel Castro and his brother Raul are still in charge. Meantime, in Florida, two Cuban exiles who have been fierce guardians of the embargo are fighting for their political lives. Lincoln and Mario Diaz-Balart, nephews of Castro, are opposed, respectively, by Democrats Raul Martinez and Joe Garcia, who are brothers despite their different names. Ann Louise Bardach, author of the forthcoming book, Without Fidel, has written about the election for the Daily Beast.com.
