Every woman should read this book, to remember how it was in the bad old days (and how it could be again), and how the law creates a structure within which we all live and how it cuts against women so often. The book is replete with insights into the two principals and, most importantly, how the Court works. The Court is in a sense the ultimate political body, but in a positive way: the nine justices share a common framework of legal understanding to which they bring to bear their own backgrounds, experiences, understandings of how the world works. Hirshman is convinced that life experiences count for a lot in the law and that they should, and therefore that O’Connor and Ginsburg (and later Kagan and Sotomayor) brought necessary perspectives to issues like abortion access, sexual harassment and gender discrimination, and workplace law. She demonstrated how Ginsburg and O’Connor used their sharp legal analysis (and political courage more so in Ginsburg’s case) *and* their interpersonal skills and political strategy (more so in O’Connor’s case) to prevail in some cases, or at least lay the foundation for another day. And they did all this while feminists debated whether equality lay in the fact women are the same as men or the fact that women have differences that ought to be brought to bear on public and private life. A fascinating story and becoming more important every day of the Trump Administration.
