The reason is Bush carried the Hispanic vote 54-46 and the Cuban vote by more than 3-1. His immigration policies helped with the non-Cuban Hispanics and his strong stance against Castro got the Cuban vote. Also, a Cuban-American was running for Senate, which helped pull up the turnout of the reliably Republican Cubans. The hurricanes helped too, because the federal government was handing out aid constantly down in Florida. Lastly, you can't understimate the importance of your brother being a VERY popular governor.
