@parados,
It isn't working because the govt doesn't allow access to that database. Did you not see the article on Florida and how they have been seeking access to verify citizenship?
I already show an ID and get a background check when I purchase a weapon, no such background check is done when you register to vote. So we are already applying a stricter application of an Amendment.
For the situation to be equal, I would fill out a form that says I'm not a criminal and then I sign the doc as an oath stating that I'm not a criminal. That is the equivalent of what is taking place with voter registration and voting.
