I do know when the state legislature in Kentucky wanted to change the murder laws to further encompass unborn children, feminists/abortion activists protested, saying that it was opening the door for prosecutions against abortion doctors. As for the public record of NOW or NARAL, I am unsure.
I also don’t know these details, but I do know that the abortion industry is VERY anxious not to recognize the killing of an unborn fetus as murder, or even as a crime, because it tends to throw a bad light on abortion.
Where they run into trouble is that obviously the mother did not “choose” to murder her child in these cases. So it’s not a woman’s choice. But calling it murder still makes them very uncomfortable, because it suggests that maybe the fetus is a human being.
