As others have noted, those claiming that the "big fear" with "REAL ID" is revealing our Social Security numbers (claiming that's why we should embrace the program), are waving a big fat RED HERRING in our face.  The reason to refuse to participate in the "REAL ID" program is unrelated to S.S. numbers.  "REAL ID"  is a Federal attempt  to get the 50 states to implement a universal ID for The Feds.  If you think a domestic passport is what we need to keep us safe, and make your life easier - embrace the concept - if you value the freedoms you enjoy because you live somewhere in the United States of America reject REAL ID.  Just my opinion of course.
