In order to eliminate or at least minize illegals getting into our country, all it will take will be the simple act such as changing the law that gives citizenship by birth. Just because you are born here does not automatically make you a citizen, but that is not what the law says. Another thing is to start eliminating those program that are set up to help out illegals, many states have different programs set up to teach vocational skills, welfare aid, etc. My motto is "Work hard, there are millions of illegals counting on your taxes to help them out"
Just my .2 worth.
