The National Guard's primary duty is to guard their part of the nation. They're trained, properly equipped, not subject to bribes, have an inviolate chain of command, answerable to UCMJ, can't form unions and their budget is secure, not subject to political trifling. Using them for what they're for should not be considered a radical idea.
I already explained self-deportation. No roundups, no cattle-cars, no expense - just some scofflaw employers serving easy time for violating laws that have been on the books for many years.
Ok by me. Take it to Congress and get it enacted. By the way, will the laws against employers be state laws or federal? Can you do this without violating their US and or state constitutional rights?
