Princeton professor Robert P. George has an excellent essay that spells out just how extreme Obama's position on abortion is.

What kind of America do we want our beloved nation to be? Barack Obama's America is one in which being human just isn't enough to warrant care and protection. It is an America where the unborn may legitimately be killed without legal restriction, even by the grisly practice of partial-birth abortion. It is an America where a baby who survives abortion is not even entitled to comfort care as she dies on a stainless steel table or in a soiled linen bin. It is a nation in which some members of the human family are regarded as inferior and others superior in fundamental dignity and rights. In Obama's America, public policy would make a mockery of the great constitutional principle of the equal protection of the law. In perhaps the most telling comment made by any candidate in either party in this election year, Senator Obama, when asked by Rick Warren when a baby gets human rights, replied: ''that question is above my pay grade.'' It was a profoundly disingenuous answer: For even at a state senator's pay grade, Obama presumed to answer that question with blind certainty. His unspoken answer then, as now, is chilling: human beings have no rights until infancy - and if they are unwanted survivors of attempted abortions, not even then.
