Today, the Guttmacher Institute reported that the abortion rate in the United States reached its lowest level since 1973, the year that the Supreme Court decided Roe v. Wade. But to the extent that either side can claim any victory in this landmark, credit should go to reproductive rights groups, not anti-abortion activists. In fact, foes of abortion have opposed most every single public policy that contributes to lowering the abortion rate in America. Of course, the best example is contraception. Conservatives have been apoplectic about a requirement under Obamacare that private insurance companies must provide affordable access to contraception.
