"I think it very important that you view the vacancy created by Justice Souter's resignation as an opportunity to lay the groundwork for a series of appointments that will gradually move the Court in a pragmatically progressive direction. Neither Steve Breyer nor Ruth Ginsburg has much of a purchase on Tony Kennedy's mind. David Souter did, and it will take a similarly precise intellect, wielded by someone with a similarly deep appreciation of history and a similarly broad command of legal doctrine, to prevent Kennedy from drifting in a direction that is both formalistic and right-leaning on matters of equal protection and personal liberty."
