Would a national U.S. citizen identification card help to fight illegal immigration?
Not really. All aliens in the U.S. already are required to carry a passport and visa, or their permanent resident alien card with them at all times. Aliens in the U.S. already have their own “national ID card,” but the problem is that no one in law enforcement bothers to check them anyhow! Forcing United States citizens to have a new “citizen ID” is not necessary. Every state in the union already issues their own ID in the form of a driver’s license. Until the INS or some other law enforcement agency starts checking aliens for proper documents systematically, there is no need for another form of ID for U.S. citizens.
