Well every poll I have seen has Trump leading amongst Cubans and Venezuelans. Even the fake news polls.
Older, first generation escapees from Cuba, stand heavily one way, but the younger generation leans prominently the other way. Right now, the overall effect is a muted lean to the right, but it has steadily been moving to the left and will likely continue that direction as the younger folks become a larger portion of the adult population.
The Bay of Pigs was in 1961. Castro seized power in 1959.The Cubans who fled Castro have already had children, grand children and great grandchildren etc since. And Cubans still support Trump. To suggest it's only the old Cubans who support Trump doesnt quite match the facts does it, given that there are vastly more children and grandchildren of Cubans who fled Castro than those who originally fled Castro. We are talking a time span of 60 years here. And Cubans overall are stollsolidly in Trump's corner because he delivered for them, whereas Obama/Biden didn't.
Trump honored Bay of Pigs veterans. What does Biden have to offer? Nothing.
