To be fair, it's virtually impossible to tell whether a text was written by an AI or not. If some motivated actor is willing to spend money to generate quality LLM output, they can post as much as they want on virtually all social media sites.
The internet is in the process of eating itself as we speak.
two major things to keep in mind
a) majority of hispanics in the US have been there multiple generations. while they may hold some varying level of ties to their family's home country, they've more or less been mostly americanized and are effectively just a different flavor of "american"
add in the fact that these are a more socially conservative people who more likely to be religious and it makes sense why they have been moving to the right. GOP could have taken advantage of this a long time ago. I think it's strange that Trump is the one to finally harness this group of people, but I guess reality is stranger than fiction
b) the US isn't stupid and it imports right-wing anti-left people. For example from Cuba or Venezuela. Miami has a massive Cuban population and they're all descendants from people fleeing the communist Castro regime. The Cubans are bred from birth to believe the Castro regime was evil and they're told all about the horrors (conveniently nobody remembers the just as brutal Batista regime, coincidentally supported by the US).
So all it takes is for there to be a connection between "democrats -> left wing -> communist" and all the Cubans turn against the DNC.
what I find fascinating is that you talk to a young Cuban who is one or two generations separated from Cuba, they have all sorts of horror stories and hatred for the Castro regime.
But you talk to an old-timer, someone in their 60s or 70s and they have nostalgia and nuanced views. Sort of like how people view the Soviet Union.
If we're gonna summarize all of this I'd just say this- assimilation. We're watching the process of how Irish went from "ethnic minority" to "white" and hispanics are going through a similar process
