Yes, but I don't think the ruling will ever be reversed!! 7 of the 9 current supreme court justices were appointed by Republican Presidents!! The supreme court will NEVER be more lopsided than it is now... and they've done nothing to reverse the ruling!!! Yet, the GOP candidates still use this to sway votes!! I don't see it!!!
I think that there are four Justices on the Court right now, Alito, Roberts, Scalia, and Thomas, who could concievably vote to essentially reverse Roe v. Wade. In fact I think it likely that they would if given the opportunity. It only takes five. One can never be sure of how a Justice will vote but the odds of ending up with a Justice who would vote to overturn the decision are obviously better if a Republican appoints one than if somebody like Obama does. It would've been hard for McCain to appoint one who would be obviously likely to do it because there's a Democratic Senate. But I think if you kind of research and recall what's been going on the past few years you'll note that abortion "rights" advocates were quite concerned about the possibility of the Court tipping on that issue.
Realistically, it would take both the election of a Republican President who opposes Roe v. Wade and substantial Republican control of the Senate to create a situation where that President could nominate someone who is almost certain to be willing to overturn the Roe v. Wade decision. The odds are against that but nothing is impossible. Many things can happen to change the political winds. But you have to be willing to treat it as a political matter for it to happen.
