if a pregnant woman leaves a red state then comes back no longer pregnant... she owes an explanation for what happened to the baby similar to a husband returning home without a wife.
if the baby was killed, she should be held responsible similar to a husband organizing for his wife’s death.
If she traveled to a state where abortion is legal and has the abortion there, she hasn’t committed a crime in the state where abortion is illegal.
Kind of surprised some people are talking along the lines of states limiting where people can travel (or even monitoring where they travel). The freedom to travel between states unmolested has been one of our core liberties since the beginning, right up there with the right to bear arms and the right to free speech.
