Great point. “Population center control” may not be as “real” as it appears. Definitely a REAL strategy, but likely implemented via artifice, fraud, and organized crime coercion as recorded historically for nearly 200 years now. Actual “liberal” or “Democrat” demographic is US is around 25% max even in most liberal states. The rest is an illusion.

The real challenge is stopping urban organized crime fuelled by illegal immigration, imo.
