Cubans are overwhelmingly Republicans and stormed the Miami Dade election office when the democrats tried to shut the door and stuff the ballot box to give it to Gore.
Most people don't realize that the immigrants who came around 1960-1965 were almost all white, almost all had direct European heritage, and most of them were well educated.
That group, literally, was the professional class that ran Cuba under Batista - the doctors, lawyers, engineers, business managers, and business owners of Cuba.
They arrived in Dade County flat broke, and within 20 years, they owned Dade County.
The second wave of Cuban immigrants, which began around 1979, was completely different.
More than half were Caribbean Blacks, many had criminal records, and most of them had very limited skills and education.
If the “NJ” in your screen name stands for “New Jersey,” then you know that huge numbers of Cubans from the second migration moved to the New York City metro area.
I've never seen voting data on Cubans broken down by date of immigration.
But I do know that the Congressional District where most Cubans live in New Jersey votes more than 75% for a Democrat Congressman.
