As such, it should not have personhood under the law. There is no need for it other than anti-abortion grandstanding. Appropriate sentencing to protect society is perfectly achievable with existing laws, and a fetus quite simply isn't a person.
I regard the late-term abortion debate as irrelevant. Even when it's legal, no one does it electively. Legislating the matter seems more symbolic to me than anything. Sure, go for it.
