I see abortion as a moral/spiritual belief that cannot be easily shaken by scientific or rational understanding. Just as people have strong beliefs in Jesus as Lord and savior, the existence of God, or even the righteousness of our current wars, abortion is based more on deep-seated beliefs, not scientific proof or rational thought.
Politics can often trump value beliefs, though,when practical considerations are factored in. For example, most Americans abhore children and other innocents being killed in war. However, most of us would probably agree that "collateral damage" is necessary but unfortunate in order to maintain a cetain degree of freedom and security (although we may disagree as to the degree).
If Roe V. Wade is overturned and some states decide to ban abortion, the practical outcome may not be one that most Americans would tolerate. Consider an outright ban in some of the poorer states. It could, in all probability, lead to higher levels of poverty and higher welfare rolls if poor women choose to keep their babies (especially in light of the fact that currently poor women have a 400% greater chance of having an abortion than other women). Converesly, if more women chose to give their baby up for adoption, many of these children are not likely to be adopted considering most couples seeking adoption want a healthy, white child. Unadopted children will add to the financial burden of these states and to America as whole. These are just two scenorios. While uncertain, the practical results of over-turning Roe v. Wade may eventually play out in favor of providing greater access to abortion than many imagine.
