"For better or worse women have been making these individual decisions about abortion for the past 25 years. If recent public opinion polls are to be believed, more women have more doubts about abortion than they did in the past. Perhaps the day will come when very few, if any, women will opt for this alternative. If that day comes, however, it will be because they as individuals decided that abortion is wrong and not the answers to their problems. It will not be because the Government imposed that decision upon them against their will. The ability of individual women to make this judgment for themselves is the real and lasting legacy of Roe v. Wade."
