Whay we have is a multifacted confluence.
1) we have a political party who is actively seeking to remake the U.S. into a communist utopia.
2)Part of that plan is for immigrants to become subscribers to that utopian vision, and not assimilate into the prevailing culture.
3) If you can’t win at the ballot box, change the voters, not the plan.
This is what’s happening. They are attempting to change the voters by overwhelming the native born and predominately white population with “browns” who are poor, poorly educated, and easily led. They are attempting now, to paint the prevailing culture as inferior. Though its superiority is plainly obvious, it is now an object of derision. Paint the target, freeze it, then polarize it, goes the Alinski version. Their defense of their warped vision is to accuse the prevailing culture of racism, nativism, xenophobia, etc.
"Multivectoral threat" in milspeak.
The "change the voter base" initiative is the boldest. The leftist-thugocratic Kirchner regime in Argentina is doing the same thing on a smaller scale using dirt-ignorant, rock-poor Bolivian Indians as their patsies, settling the Indians in voting districts where the regime is weak and the electorate represented by opposition politicians.
My point being, that the use of the same gimmick by two leftist regimes that have been in political consultation (since 2000 at least, when Clinton advisors were lent to Jose Menem), shows that this idea of diluting commonsense opposition with immigrant drone voters is being passed around among Left parties.
