Yes you can deport them all. You just have to have the SPINE to do it. Once it gets started, more will self-deport.
Take away the freebies, jobs, and ill-gotten gains and the rust back to the border will commence. But first you got to get a SPINE!
Really, spine? That's all it would take? No logistics involved at all. There are 12 million (probably more) people in this country illegally. If you wanted to get it done in 5 years, you would have to deport 6,576 illegals EACH DAY, every day including weekends. Do you really think that is logistically possible?
