It's the proper legal opinion
The FEDERAL Government has no business in abortion. It's not a FEDERAL right, it is nowhere in the Constitution either, so as the Constitution says, all other business of Government not explicitly covered by the Constitution, is reserved to the States.
Many States will still have abortion.
Truth is- Gay Marriage actually should be a State by State issue as well.
Personally, I think we should expand abortion as mandatory for all offspring of felons, male and female, no questions asked, and for anyone on Fed, Stare, County financial assistance.
