The problem is its unlikely Biden wins Latino heavy Texas and doesn't get at least enough of a boost to win Florida. Same does with suburban Austin, Houston, Dallas voters...hard to see Biden not being able to flip PA, MI with this trend happening in TX.
Texas Latinos =/= Florida Latinos. Latinos in TX are mostly Mexican-Americans who usually vote overwhelmingly for Democrats. Latinos in FL are more varied (Cubans, Colombians, Puerto Ricans, etc). Cuban-Americans & Colombian-Americans lean towards Republicans and Puerto Ricans typically lean towards Democrats.
You're mostly right.
However there's a large % of Evangelical Protestant Latinos in Texas also I'd say 25%-50% of Texas Latinos are "mixed" with Anglo.
