Some state governments have claimed that a pending compliance deadline for REAL ID requires them to tighten up their driver's licensing procedures consistent with the 2005 national ID law. (But see this.)
In fact, REAL ID is dead and the deadline is fake. More than a dozen states have statutorily barred themselves from complying, and in a rule published Monday the Department of Homeland Security extended the deadline again. This is the same thing it did last May and could easily do indefinitely.
The republic survives, and will survive quite nicely without this or any national ID law.
