What is needed is for the Supreme Court to overturn Roe v Wade and not outlaw abortion, but simply return the power to the states, where it belongs. Then, we can finally have the debates the Supreme Court silenced with the Roe V. Wade decision. Abortion can't stand up to an open discussion. You simply need to see the results of a late term abortion and you know it's wrong. Once you have accepted a late term abortion is wrong it is impossible to find a point at which it is acceptable.
Unfortunately what makes it difficult for the pro-life position is that before Roe, abortion was *already fully legal* in NY, CO, KS and HI. It was partially legal in many other states (where a hospital review board could OK it for all sorts of maternal-health reasons.) These states *had* the "debate" and decided in favor of legalized abortion.
Had Roe not occurred, most of the states would have had some kind of "therapeutic" abortion that would have included killing of the handicapped unborn as well; about 1/4 of the states would have had completely liberal laws like NY, and probably another quarter would have forbidden it except for life of the mother (like TX before Roe.)
