Is the Supreme Court working the way we want it to? If not, what has changed? Is it fulfilling the role assigned to it by the Framers of the Constitution? Has it become too powerful, too political, too what?
Of course, politics is inherently part of the judicial system. But there's a difference between saying that justices live, work, and are selected in a political world and saying that when they get on the Supreme Court they're really just politicians in robes.
