"The Court’s decision in Roe was written by Justice Blackmun, whom President Nixon appointed to the Supreme Court in 1970, and supported by other of Nixon’s conservative appointees, including Lewis Powell, who during the Court’s deliberations actually advocated lengthening the time period in which women’s abortion decision was protected—from the end of the first trimester to the end of the second. But over the course of the 1970s, prominent Republicans shifted positions on abortion, acting on alignments and framings that were already in evidence by the 1972 election. By the decade’s end, conservatives of the New Right—led by Ronald Reagan, who, in the late 1960s, had signed California’s legislation liberalizing abortion—urged fundamentalist Christians to make common cause with Catholics in opposition to abortion and in support of family values. They attacked Roe as a threat to life and family and as a symbol of judicial overreaching. Republican Party platforms began regularly to support “the appointment of judges who respect traditional family values and the sanctity of innocent human life.” With Republican presidents appointing justices who might be counted on to oppose Roe, judicial support for the decision narrowed, and by the late 1980s, Roe looked vulnerable to outright reversal. But the women’s movement continued energetically to mobilize in support of the decision, and in 1987 it helped defeat the nomination of Robert Bork, a prominent critic of the Court’s privacy decisions. Ensuing Supreme Court appointments by Presidents Reagan and Bush seemed to provide sufficient votes to overturn Roe. And yet, in 1992—during a presidential campaign in which the abortion right was a burning issue—the Supreme Court decided Planned Parenthood v. Casey, a case that both reaffirmed and narrowed Roe."
