There will not be an honest political discussion on this untile Roe v Wade is repealed and the issue is discussed on its merits only.
Indeed. The one point where I would criticize the Republicans' "partial-birth abortion" ban is that I don't think it properly stated its constitutional justification. States do, after all, have very broad powers in defining what types of homicide are or are not lawful; it is legal, for example, for a homeowner in Texas to shoot someone who is committing criminal mischief on his property in the nighttime, even when the criminal poses no immediate threat to the life of the homeowner. In other states, such action would be attempted murder (or second-degree murder, if the shooting proved fatal).
I don't know the best way to resolve the issue. Obviously it is just plain wrong that Roe v. Wade and follow-up decisions make it essentially impossible for states to restrict even "partial-birth" abortions, but I don't know the best way for Congress to return such authority to the states where it belongs.
