Contrary to what most letter writers say, the U.S. never had a constitutional right to abortion.
The Roe v. Wade (U.S. Supreme Court decision in 1973) was merely making a very long stretch between the right to medical privacy (protected by the U.S. Bill of Rights) and abortion, a stretch confirmed in a statement by the very progressive late Supreme Court Justice Ruth Bader Ginsburg.
Also, contrary to what most people say, abortion is still legal in (some) U.S. (states), including late-term abortions, which still ranks the U.S. in the list of top "progressive" countries in the world.
For example, it is more difficult, if not impossible, to abort a non life-threatening pregnancy in Europe. In Canada, such a procedure does not seem to be done in practice, while it's still fully legal in some U.S. states.
That said, if there is such a wild consensus on abortion (in the U.S.), its Congress is free to pass such law, and if the Congress is not capable of gathering a majority to do so, then such is the will of the people. Progressive (u.S.) states are also free to suggest a constitutional amendment.
No matter what, it never was a subject to be decided by a panel of an all-male, non-elected Supreme Court (in 1973).
