"Given the Court’s recent abortion decisions, adherence to “Roe” as the keystone of abortion jurisprudence appears impossible. For the Court to draw some as yet undefined and more circumscribed boundary around a surviving constitutional abortion right, thereby leaving the states free to regulate expansively on abortion, seems improbable at a time when some of the Justices increasingly disavow the construction of complicated, quasilegislative constitutional schemes such as the one established in “Roe” itself. The return of criminal abortion is a distinct probability. More pointedly, the states themselves have begun to act as if its return is inevitable."
