A few hundred dollars. I have celebrity and poker player names, as well as a few politicians. The name is a bit long and she isn't really a lightning-rod. However; all of the potential Supreme Court nominees this last go-round were taken well in advance of the decision....mostly by speculators. It would be best served as a legitimate site; not a site that capitalizes on type-in links (because there won't be too many). She's been on the court for a while, but you would hardly know it if you didn't pay attention.
In short, it is the probably the kind of name that you renew for the next ten years in the hopes that someone associated with her wants to pick it up. In that case you should be able to get a few grand. Individual names are unique and cannot be duplicated. I wouldn't sell my name for 2K, and I'm not even famous.
