Probably it will become more homogenous no matter what some would prefer. Knowing some Hispanics as I do, I don’t think they’re going to be very accepting of a leftist “minority” identification, and certainly not very long. I’ll grant that most Hispanics I know are of Mexican origin. Some are pretty “Indio” in appearance, some are very “white”, some are in between. Looking at a local newspaper, I note that among the homecoming queen and her attendants of a local high school, three are indisputably “Anglo”. One is indisputably Hispanic,(by name) and almost certainly of Mexican origin. The kids themselves elect those girls. The Hispanic one is “browner” than two of the others, and about the same as another “Anglo” girl, except for hair color. And this is in an extremely “white” part of the country, went 80% for Trump, and is pretty “southern” culturally. And yet, the high schoolers elected a Hispanic attendant. One out of four.
Despite Dem desires to keep all Hispanics “on the plantation” politically, I don’t think they’ll stay there any more than the Irish or Italians did. And as I have mentioned before, the Mexicans I know are more “capitalist” than most Anglos.
Seems to me Trump did the right thing in refusing to endorse illegality and putting the question right where it ought to be; with congress. If congress is too stupid and/or cowardly to do what it ought to do, which is put most on a citizenship track and deport the ones with criminal records, then shame on them.
