The law will only correct the issue if the states go along with it. If New Jersey decides not to accept the grant money, they don’t have to set up a program for rights restoration, and anyone unjustly inserted into the database by the new mandate will have no recourse but to move out of the state to one which does have a program.
Poor example. New Jersey sucks (I’m from there), as do a few other states who abuse the second amendment rights of the people who live in them. A few states will fight to the end against the rights of their people, New Jersey being one of them. If the federal government passed a law mandating the correction of the records, because forbidding a person to purchase a certain object is regulation of interstate commerce, New Jersey and its ilk would suddenly find limtitations to the commerce clause, and probably support states’ rights.
Whatever is done, a few blue states will oppose it and many may refuse to comply. I’d rather get my foot in the door than wait until it is open all the way. Incrementalism works in our favor, too.
