Posted below is an excerpt from an article that provides just a brief summary of the concerns - which are much more than keeping abortion legal. If you think that is all that is at stake (as I did), you need to look into the issues more deeply.

"Barack Obama and John McCain differ on many important issues about which reasonable people of goodwill, including pro-life Americans of every faith, disagree: how best to fight international terrorism, how to restore economic growth and prosperity, how to distribute the tax burden and reduce poverty, etc.

But on abortion and the industrial creation of embryos for destructive research, there is a profound difference of moral principle, not just prudence. These questions reveal the character and judgment of each man. Barack Obama is deeply committed to the belief that members of an entire class of human beings have no rights that others must respect. Across the spectrum of pro-life concerns for the unborn, he would deny these small and vulnerable members of the human family the basic protection of the laws. Over the next four to eight years, as many as five or even six U.S. Supreme Court justices could retire. Obama enthusiastically supports Roe v. Wade and would appoint judges who would protect that morally and constitutionally disastrous decision and even expand its scope. Indeed, in an interview in Glamour magazine, he made it clear that he would apply a litmus test for Supreme Court nominations: jurists who do not support Roe will not be considered for appointment by Obama. John McCain, by contrast, opposes Roe and would appoint judges likely to overturn it. This would not make abortion illegal, but it would return the issue to the forums of democratic deliberation, where pro-life Americans could engage in a fair debate to persuade fellow citizens that killing the unborn is no way to address the problems of pregnant women in need.

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."
