Lol, that's what conservatives think about Sotomayor and Jackson, and looking at their comments during oral arguments as well as their opinions, I think they have a point. (Kagan is generally a more rigorous thinker.) Actually most cases argued before the Supreme Court still have a unanimous or almost unanimous outcome, or are denied cert (which would often indicate a unanimous opinion were it to be ruled upon). It's only in the more controversial cases where you're more likely to read the more blatantly political arguments.
