In our Constitutional Republic, abortion should be a states rights issue. The Constitution says nothing about abortion. Thus the people should decide. That means the states.
Try reading the Preamble and the Fifth and Fourteenth Amendments, with comprehension.
The only way you can reach your conclusion is to A)ignore the Ninth Amendment, and B) like the judges who decided Roe, have concluded that children in the womb are not "persons."
By the way, if you got your way, most abortions that occur in America today would continue to occur. How pro-life is that?
Additionally, to conclude that a child in the womb is not a person is to remove the only possible legal, moral or intellectual argument against Roe, or the overturning of abortion in any of the several states.
