Less than two weeks after David Souter announced he’s stepping down from the Supreme Court, the online bookies at Intrade have started selling contracts over the question of who will replace him. So far, ten of the fifteen possibles are females, indicating that early investors are confident the next justice will be a woman. Sonia Sotomayor is the most favored candidate, with a predicted 28 percent chance of sitting on the top bench. Elena Kagan follows with 23 percent, then Diane Pamela Wood and Kimberly McLane Wardlaw.
