We heard 10,000,000 during the Reagan Years. Plenty of time to raise 2.5 kids per couple. Are the children of illegals legal? There has been a steady flow across the border since.
I heard 12 million during the last Clinton years. My guess is 30 million illegal aliens now but even worse is that they are mixed into families of legal aliens/immigrants. So these legal green card immigrants have an interest in keeping the illegals here.
So many combo families now with say a legal wife and illegal father with half the children being legal US citizens due to being born here and the other half are those BS “Dreamers” who were smuggled here
Just think of the movie The Blob
