First, secure the borders of the United States. I'm not sure why that is so difficult for politicians to understand. Even in past centuries when Ellis Island was open and processing people who were entering the country there were limitations regarding entry. Secure the borders and make sure the people living around the borders are safe.
Second, enforce the law. Again, it seems axiomatic that if a law is on the books that is meant to regulate some behavior, the first and foremost consideration in controlling that behavior is to enforce the law that has been written to regulate the behavior. That is not rocket scientist thinking; anyone but a politician knows that is common knowledge.
Third, keep people safe. Not just the people who live in the border states, but all people who are suffering at the hands of people who use stealth techniques to slip into the country and pillage the resources.
Fourth, complete the first, second and third priorities above so as to prevent the same situation we are experiencing now from happening five, ten or fifteen years from now. Those who have been elected in Congress as well as the Administration need to take a common sense approach to this issue and do what is needed to secure our borders, enforce the laws of our land instead of making countless new ones, and look after our resources during the process. It is your responsibility so please get it done.
