I must have been exposed to an enclave, because the ones I have known were so anti-Castro, Communist, and Democrat that they would nearly spit on the ground inside a house at the mention of the subject.
Sadly, though, you may be right in some respects, given the huge numbers of certain types of people who were released to leave in the various exoduses...grifters, criminals, no-loads.
Democrat constituency.
There is a very large concentration of 1980+ Cubans in the metro New York City area.
150,000 in the 2010 Census - the largest group outside south Florida.
Every Congressional District in that region is massively Democrat.
