Yes I have read that before, about the SCOTUS decision was based on the fact abortions would be limited and a minority decided procedure. But I am not a legalese, so I have not read up on it my self. I guess it is really left up to the States to narrow the definition? Of course it doesn't help when a neighboring State has more liberal abortion laws.
A limited right would be better than an unlimited one, but as you say, with transportaion as easy as it is, the number of abortions would not go now as much and I would wish. Millions of Americans are now persuaded that abortion is, like divorce, an unpleasant but necessary thing.
