What you have to understand is that there was more than just "The Wall" to Trump's border control strategy, there was effort to create a full spectrum plan to make it too much of an ordeal for invaders to be comfortable and stick around. And about partway through his administration it did bear fruit, I saw that myself. Foreigners vanished from the stores, workers in various crafts or services were now black, white or American Latinos, housing became more available in some markets. Rather funny to see former invaders griping about it across social media too - suitable for printing out & framing. After the reign of FJB began, here we are, like in the first sentence in your post, once again wading through people in stores speaking foreign languages, not only Spanish or Portuguese but now with addition of Eastern European dialects too. The difference between now than from then besides Trump being out of office is that there is a whole different level of chaos to contend with, not just domestically, but across the entire world. I do not see how one little US domestic election is going to reset all of that since at the speed of how things are imploding or exploding, whichever term that fits, I'm expecting a whole different world order to exist by the time that rolls around. At this point my plans are to anticipate and survive what's coming. You should do the same.
Agreed.
The scale of what would be required is more that could be accomplished by just electing Trump and majorities of GOPe Swampers.
In his first term they sabotaged the Wall, and in his second they will certainly sabotage any large scale deportation.
My view, it would have to be done at the State level. But you look at Kemp et al. these donor controlled Swamp Men are not going to mass deport the wage reducing illegals.
