Most Hispanics in south Florida which are composed of Cubans consider themselves white. You couldn't tell the difference from a picture.
They may consider themselves white ironsides, but whites don’t consider them to be whites. Indeed, white conservatives consider them to be lower than blacks.
I remember there was a telling moment in All in the Family. Archie Bunker is trapped in an elevator with a black and a Hispanic. He is having a heated argument with the Hispanic about equality. The Hispanic claims
“I as fully equal to you in everything, Mr. Bunker.”
Bunker retorts
“Equal to me? You ain’t even equal to him (pointing to the black)”.
There is plenty of bad blood between Hispanics and white Republicans. That is why a great majority of them vote Democratic (though not in as lopsided numbers as blacks do).
