Roe v. Wade is not a law, and as such it cannot be repealed.
It can be overturned, but it would be much better to overturn Griswold v. Connecticut, which was another, worse power grab by an out-of-control court, and which led directly to Roe v. Wade.
Wickard! Raich, Kelo.
Roe V Wade decision was based on doctor - patient privacy, as I understand it. There has never been a supreme court ruling saying that a woman is entitled to an abortion.
