With the move in the Senate to revive our moribund national ID law, the REAL ID Act, under the name “PASS ID,” it’s important to look at whether we’re still dealing with a national ID law. My assessment is that we are.
First, PASS ID is modeled directly on REAL ID. The structure and major provisions of the two bills are the same. Just like REAL ID, PASS ID sets national standards for identity cards and drivers’ licenses, withholding federal recognition if they are not met.
