I do think some Latinos having true conservative values has a lot to do with it, but I think people forget that a great number of these voters are actually phenotypically White or very close to it. They probably see themselves as different from brown/mestizo latinxs and are angling to be on the right side of white supremacy and eager to reap all the fantabulous benefits of being white-adjacent.
"Porque no? Mira..I am White too, yes? So let the mestizos be the maligned minority.
Viva la Trump!"
Some of them are probably pretty stoked to have a shot at being the ones holding the trigger.
