Hilzoy in Washington Monthly makes the good point that besides endorsing a right to privacy in the Constitution (heretical among those who oppose Roe v. Wade), she endorsed states protecting that right:
If there is a right to privacy in the US Constitution, then protecting it is a federal issue. It has to be. You just cannot say that there is a right to privacy in the US Constitution, but that what to do about that fact should be up to the states. Not if you understand what the Constitution is, and how our system of government works.
