If Bush won't enforce existing law why would you expect him to deport illegals who don't register?
You don't seem to understand how the program would work. There will be a deadline to register; if you're here after the deadline and not registered, that would be the one thing needed to send them back; then, if you are registered, you would have to obey all the rest of the requirements; if not, you're gone, too.
Don't you understand that they are trying to change the rules from the bottom up with the game already under way?
And he is TRYING to enforce the existing laws; they're getting more now than they ever had. He's doing the best he can with NO HELP, obviously, from YOUR representatives and others in the government. He's not God.
No registration: no benefits, no government assistance, no driver's license, etc.
