Most of the people opposed to this thought it was as creating some kind of internal passport. What it was really doing was setting a standard for state ID and proof of identity.
The standard is useless if you don’t have control of your borders.
During a break-in in Florida, my raised-seal birth certificate & social security card were stolen. I know these ID documents are being used, since I occasionally get demand notices from the IRS demanding the taxes the illegal who is using my ID isn’t paying.
Once an illegal has this documentation, he can get a passport & driver’s license.
