Why would you say that? The next Democrat administration is going to open the borders.
If you think about it, immigration law does not require a Constitutional amendment. If we get another 2008, where Democrats control both the legislative and executive branches--which is entirely possible in the next decade--I could definitely see them doing something like this.
In the past, they at least had to worry about "appearances." I think they're all well beyond that now. They'll crank out bills day and night, and have them en masse, on the President's desk well before the end of the administration's first 100 days.
We'll have open borders, Obamacare 2.0, some kind of attempt at gun control, and tax increases on everyone. (Though they'll portray it as "only the rich are being soaked.")
If they get any crap from the Supreme Court, they'll just pack it with their own judges.
We live in very precarious times.
