Hey, murder used to carry that penalty...
Look, I get it. I believe that abortion is murder. However, if you are a politician, or if you write opinions for the leading conservative magazine, you don't answer hypothetical questions like that on the record. For that same reason, you will never hear a liberal commentator share that it is their party's best interest to keep as many people as possible on public assistance. On rare occasions you have heard an honest one say that they were rooting against our troops in Iraq. But you get the point.
The answer to this question is as follows: "The first step is to pass laws to outlaw abortion with the exception of cases of rape, incest and where the life of the mother is physically endangered. We are a long way away from that point. Until we get there, there is no reason to address penalties or what comes next."
What Williamson just did was provide a useful talking point for swing voters because his ego was threatened.
