What's kind of ironic, is that with dims concerted efforts to think they are flooding the country with new democrats, they actually are adding a demographic that is so tended toward social conservatism, might in the long run (50-100 years) backfire on them. Look at all the red this election cycle along the Texas border.
I have always been a purveyor or adherent to the "Laws of Unintended Consequences" Club. And this is a big candidate.
Disclaimer: No way am I proposing or endorsing the Biden/Harris border disaster, just highlighting future consequences after we are long gone.
