By today's politically polarized standards, the Supreme Court's momentous Roe v. Wade ruling was a landslide. By a 7-2 vote on Jan. 22, 1973, the justices established a nationwide right to abortion.
Forty years and roughly 55 million abortions later, however, the ruling's legacy is the opposite of consensus. Abortion ranks as one of the most intractably divisive issues in America and is likely to remain so as rival camps of true believers see little space for common ground.
Unfolding events in two states illustrate the depth of the divide. In New York, already a bastion of liberal abortion laws, Gov. Andrew Cuomo pledged in his Jan. 9 State of the State speech to entrench those rights even more firmly. In Mississippi, where many anti-abortion laws have been enacted in recent years, the lone remaining abortion clinic is on the verge of closure because nearby hospitals won't grant obligatory admitting privileges to its doctors.
