One of the loopholes offered by Roe v. Wade is that a state can define an unborn child as a person–something never done–and Roe could thereby be overturned. Such efforts are usually squashed by the NRLC (in the interest of self-preservation) and the USCCB (out of fear of bringing the abortion issue to a head and causing “social distress”).
Now, legislators in seven states are promoting amendments to their state constitutions that would grant personhood status to unborn children. Five states have bills in theirs legislatures to that effect: Maryland, North Dakota, Montana, South Carolina (yay!) and Alabama. Oregon and Mississippi are doing petition drives.
