What makes you think that will be the case? Puerto Ricans on the island don’t follow the same voting/ideology trends as those in the north-east U.S.
And recently-moved Puerto Ricans in southern states are more conservative than those who arrived in the 50s to New York and what not. In fact, everything indicates that Florida Puerto Ricans swung for Trump in the last election, just like they did for W in 2004.
My niece is married to a Puerto Rican.
The whole family are virulent leftists.
