Naturally, Democrats campaign against Republicans who want to scrap Roe v. Wade all the time. But one curious thing about McCain is that since pro-choicers and pro-lifers alike seem confused about the fact that he's pro-life he's had to be unusually explicit about his intentions in this regard. Normally, candidates kind of dance around the issue and offer vague formulations about "strict constructionists" that are understood by people who care about politics but go over the heads of most people. McCain, by contrast, is really pinned down.
