The thing is, this guy is such a good advocate, and has this tempermant where he can and will take any side of an issue and build an argument to support it, in his role as advocate, that he is just too damn good at answering these questions. His answers re: Roe are amazing. He's walking a line and no one knows what to make of it. He's not simply saying "I can't answer that." He's approaching it, he discusses stare decisis, privacy, etc. But he leaves you guessing.
Consider, if you were presenting your case before the court, wouldn't you want to face a court where you feel you have a chance to win if your case in properly presented? I think in any case Judge Roberts hears, both sides would be able to walk into court with that feeling. The same can not be said for many judges, which is why I consider this man to be a rare jewel & our court system will be enriched to see him elevated to be our Chief Justice.
