How could a state, as opposed to Congress, take the lead here? The issue is the language of a federal law and an anendment to the U.S. Constitution. Only Congress could legislate to stop birthright citizenship for children of illegal aliens, tourists and other non-residents.
I foresee a state going rogue, so to speak, especially in light of Obama ignoring the SCOTUS today in the AZ case.
Suppose state ‘X’ unilaterally passes a law decreeing that any anchor baby born within its borders is not a U.S. citizen? Force the Feds to go after them. Play the game the way Obama does.
