Justice O'Connor and the Pragmatist Movement
Justice O'Connor's role in this revolution has, perhaps, been even more sublime than one might think. Pragmatism has worked some ridiculous results such as relying on treaties the U.S. expressly refused to sign, making up constitutional doctrines, and throwing out direct precedent. But the O'C is not associated with any of these deeds.
Instead, her version of pragmatism has been more in the vein of Judge Posner, although without the economics. The two of them produce opinions the result of which people generally find sensible--most people probably agree with her most of the time. What this has to do with interpreting a Constitution is still a mystery to me, but at least she's not out of touch with reality as the "hopeless four" seem to be.
What this may or may not have done is garnered considerable moderate and conservative support for the idea of pragmatism because the outcomes are often or mostly sensible. She is a figurehead for the politically conservative/jurisprudentially liberal demographic--a group whose focus is the views of the judge and the virtue of the outcome rather than reliance on structure and text. This group is playing with fire with names like Gonzalez and McConnell who both have some appealing views but are not necessarily committed to the text and history of the Constitution.
I hope that this influence has not been successful enough for those who have less trust in the structure of the Constitution than they have in 9 lawyers to support a new Justice whose supposed political views or party affiliation they share. I suspect that the Souters and Kennedys have made it clear enough that this is a bad idea.
