Cain has outlined his four problem solving - including empower the states to do what the federal government cant and wont do - as FAR BACK AS 2007 and has reiterated it ALL ALONG In this election cycle.
Solve FOUR problems: 1. Secure the border 2. Enforce the laws on the books 3. Encourage the path to citizenship already in place - starting with entering the country LEGALLY. 4. Empower the states to do what the Federal government cant
Cain is not asking states to CHANGE the federal law but enforce the laws on the books. The laws on the books are NOT AMNESTY.
