Not if states that ban abortions forbid out-of-staters from coming there.
I am sure that law would stand for a day or two before it was struck down by a court.
I don't understand what you are saying. I thought the other poster was suggesting that pregnant women who wanted abortions but lived in states where they are banned would go to states where they are available.
You seem to be saying that women from other states would be prohibited from entering states with abortion bans. I don't get the purpose ... can you clarify?
