The 14th amendment took the definition of citizenship out of the hands of the states, and the language of the amendment makes personhood an unavoidable federal issue, since the amendment requires equal protection of all persons.
The federalism/states’ rights approach to abortion is inoperative.
Since the federal "solution" to the abortion issue has resulted in a holocaust of 50 million preborn babies since 1973, why should a return to the pre-1973 approach of prohibiting abortion on the state level be rejected now in favor of another federal "solution"?
The states CAN address the issue, if we had politicians with any leadership, guts and intelligence.
