I have noticed something interesting. It seems that Latinos seem to vote differently based on where they live. I'm not talking about what country they are from but where they live.
For example California had a much more solid Latino vote for Biden than in Texas. These states Hispanic/Latino population are heavily Mexican American. I've heard that in New York and Florida, Puerto Ricans for example differ dramatically when polling each group separately. Here are some examples with both actual numbers and shift vs 2016 in Puerto Rican areas:
This seems to track along each state's political status generally (Florida is an outlier because of its large Cuban population which supports Republicans more because of communist history). What causes this? Is it that people choose where to live based on this? Historical ties? Something else?
Extra: I think it is people don't really vote ethnicity as much as they do for beliefs. For Black voters it is different because their ethnicity is tied to certain political issues like Black Lives Matter.
