Yesterday's USA Today ran this op-ed by South Dakota state representative Roger Hunt, the prime sponsor of South Dakota's abortion-ban bill.

Excerpt:

In the 33 years since the U.S. Supreme Court decided Roe v. Wade, its landmark decision on abortion, medical and scientific studies have produced a wealth of credible information about unborn children, fetal pain and post-abortion problems experienced by women, information not considered by the court. DNA studies clearly establish that the unborn child is not a glob of tissue but is a human being, separate and distinct from its mother. Abortions terminate the lives of unborn children.

In 2005, South Dakota created a 17-member state task force to gather information and evidence about abortions. The task force received testimony and materials from many national and international medical and scientific experts on abortions and unborn children, and more than 2,000 affidavits from women who had had abortions. The task force concluded that life begins at conception and that abortions harm women. Neither of these facts was considered or contemplated by the Roe court.
