They tried this in the Bush 2 ...turns out all those GOP owned meat packing houses, agribusinesses and developers need those illegals to do the work...
That's the dirty little secret...the GOP KNOWS we need the illegal labor...they are not doing anything REAL about it like your first point....what you see is just a smoke screen for the rubes...
Don't believe me...just Google DT - he uses illegal aliens at his properties....oh and Chinese steel...
