"Justice Ginsburg almost got a chance to fill in what she saw as Roe’s missing piece. In 2007, she wrote an opinion in Gonzales v. Carhart, a challenge to a type of late-term procedure, that squarely framed the constitutional right to abortion in terms of equal rights for women. But Justice Anthony M. Kennedy joined the court’s four other conservatives to form a majority, leaving Ginsburg with a dissent, which had the force of her ardent feminism but not of law. In 2009, when I interviewed Ginsburg for this magazine, she said her main concern about abortion was the lack of access for poor women (because the court decided, in 1980, that Congress could forbid the use of Medicaid for medically necessary abortions). I asked if repositioning Roe on the basis of women’s equality was on the feminist wish list. “Oh, yes,” she said."
