The GOP needs to wake up and smell the coffee and stop letting the xenophobic fringe set the agenda.
Deal with the illegal immigration problem as it exists and not as you wish it was. Accept the fact that the "fence" will never exist, and deporting ~20mil illegals will never happen.
What does need to happen is that order and control must be imposed on the illegal population that now exists in America. Document 'em; make 'em pay taxes; limit their burden on resources; and send 'em packing when they can't support themselves.
