The fence will go along way to helping ICE. It's rather simple and inexpensive. As long as the mehican gov't does little to help, the fence is a must. I will support no plan that does not include sealing the border. Politicians words mean nothing in this arena. If they did, we'd be enforcing the laws as they stand now --and the problem would be a much more manageable one.
You will never seal the border completely unless you wish a soviet style neo-berlin wall.
A guest worker program is much easier to enforce and frees up resources to go after the real bad guys and also I wish to follow the Reagan model of wishing to tear down walls and not building them.
