Get real. I suspect illegals are like bears- there are about twice as many as you think there are without a definitive way of knowing. With bears they can do a hair snag DNA study over 3 years and extrapolate from there fairly accurately.

Short of everyone going the "Show me your papers" bit , I don't think illegals will ever be counted accurately, much less controlled to any effective level.

Certainly not with libs in charge.
