I oppose any abortion with every fiber of my being.
That being said, I also believe in the Constitution our Founding Fathers gave us, and I believe that just as with murder, abortion laws MUST be a matter for each individual state.
I agree with you that murder statutes are state issues, however in this case alone we're dealing with a 14th amendment issue if we define the unborn baby as a person. It would outlaw the practice in the whole nation. IMO it is a very limited, distinguishable set of circumstances that justifies federal action.
