In his recent travels, he (Giuliani) has directed questions on the issue toward a discussion about judges, saying he would appoint jurists who believe in interpreting, not making, the law: judges, he said, like Chief Justice John G. Roberts Jr. and Justices Antonin Scalia and Samuel A. Alito Jr., who he has said he believed would place limits on Roe v. Wade.
Giuliani Shifts Abortion Speech Gently to Right The New York Times
Until I find evidence that he doesn't mean it (and I've been digging), I will give him the benefit of the doubt. They say a man is known by the company he keeps. Rudy Giuliani is keeping some pretty good company these days, including the 3 guys he mentioned there.
Limits on Roe are not limits on abortion. There are judges that are are "in the same vein" as those judges who might not vote to overturn roe (we don't even know if Roberts and Alito would vote to throw it out, and we can only hope they will vote at least to limit it in some ways).
If Roe was gone tomorrow, you'd still have to fight state-by-state to convince people that abortion was wrong and should be illegal, and Gulliani would be a loud, popular voice saying abortion is OK and we shouldn't mess with it.
