By now, liberal interest groups no doubt have extensive dossiers on the non-squishy frontrunners for the next open Supreme Court seat, and will be ready with attacks immediately if one of these individuals is nominated. In turn, it would make sense for the Republicans to outmaneuver these groups by nominating a "dark horse" who hasn't received extensive attention. My personal dark horse favorite is my colleague Ron Rotunda, one of the nation's leading scholars on both legal ethics and constitutional law. I'm sure Ron and I would have many disagreements on various things, but he'd be a superb Justice. I'm sure folks have other ideas for dark horse nominees, so I'm opening comments.
