Well, seems to me that this:
2) the Congress recognizes that each State has the authority to protect lives of unborn children residing in the jurisdiction of that State.
Pretty much sums it up. The state has the authority to protect lives of unborn children. If the state chooses to allow abortion, it is within it's rights.
But we could also point to the 'we the people act':
he Supreme Court of the United States and each Federal court--

(1) shall not adjudicate--

(A) any claim involving the laws, regulations, or policies of any State or unit of local government relating to the free exercise or establishment of religion;

(B) any claim based upon the right of privacy, including any such claim related to any issue of sexual practices, orientation, or reproduction; or

(C) any claim based upon equal protection of the laws to the extent such claim is based upon the right to marry without regard to sex or sexual orientation; and

(2) shall not rely on any judicial decision involving any issue referred to in paragraph (1).

And to top it off, here are the crimes (and only these crimes) that Ron Paul believes should be federal crimes (backed up by the 10th amendment of The Constitution):
there are only three federal crimes: piracy, treason, and counterfeiting. All other criminal matters are left to the individual states. Any federal legislation dealing with criminal matters not related to these three issues usurps state authority over criminal law and takes a step toward turning the states into mere administrative units of the federal government.
