I remember posters saying it when I first started on JPP. Maybe they got their figures here.
"Under the Obama administration, the Border Patrol has been essentially incapicated,
Obama's DACA amnesty has been issued, the
child illegal alien invasion has occurred, and deportation numbers have been fudged. It would be reasonable to project that if 20 million illegal aliens were present in 2005, 38 to 40 million illegal aliens could certainly reside in the United States in 2014."
Indeed, 38 million to 40 million illegal aliens were estimated to reside in the United States in 2007 - see
Illegal Aliens: Counting the Uncountable by James H. Walsh, The Social Contract, Summer, 2007.
