Because Reagan later openly admitted publicly that it was his greatest mistake as President and Ryan is to stupid, as are his supporters, to learn the lessons of history.
Since we saw the results of that amnesty and the trouble it caused, only a liberal would bush for one that dwarfed it in scope and only an idiot would support such a person. Because that person would be supporting a man to destroy their country. That is idiocy.
Actually immigration reform is really very very very simple.
All that needs to be done is cut off the magnet which attracts illegals.
Pass a law which gives automatic prison sentence of 5 years to the CEO of any outfit which hires illegals.
90% of illegals will self deport. Tax payers won’t even have to pay for their return flight.
That will make the job of finding remaining illegals 10 times easier.
