There will always be at least one State with legal abortions. The middle to upper-class folks will want someplace to send their daughters on "vacation". Europe will suffice for the rich and super rich.
I doubt Maryland will ever ban abortion and between cheap airfare (i.e. Southwest) and its position on border between North and South, most women of reasonable means will still be able to get an abortion. Not to mention places like New York, California, Mass., Hawaii, etc.
I think Europe has more restrictive abortion laws than we do...
Anyways abortion won't be "outlawed" in the US. Massachusetts (heh) has it in their constitution!!
I remember when it was exactly that way. I'm not sure why returning to it would be "progress".
