"Today, as in the early 1970s, the American public appears to have decidedly mixed views on abortion. In a Gallup poll in May, for instance, only 23% of those surveyed said abortion should be “legal under any circumstances,” the rule set by Roe vs. Wade. Only 22% said abortion should be “illegal in all circumstances,” the rule that could take effect in many states if the Supreme Court were to overturn Roe vs. Wade. The largest group -- 53% -- said abortion should be “legal only under certain circumstances.” But Roe vs. Wade foreclosed this middle course -- for the states as well as for the court. It does not give states the room to adopt what might be a popular compromise: permitting abortions during the first three months of a pregnancy, but not afterward. Nor does it permit states to authorize only “medically necessary” abortions, a reform idea of the late 1960s."
