http://www.scotusblog.com/2010/06/everything-you-read-about-the-supreme-court-is-wrong/Ideologues on both the left and right, as well as the public generally, frequently repeat their own received wisdoms that the Supreme Court is an easily categorized institution and that the Justices are committedly “liberal” or “conservative,” with Justice Kennedy as the lone swing vote. Liberals and conservatives also consistently accuse their opposites of being “activists,” a point vividly on display in the Senators’ opening statements in the Kagan confirmation hearings. The just-completed Term proves, I think, that those generalizations are often misleading or outright wrong.
Interesting breakdown of the ideologies of the current court, and how the 'current wisdom' of how the court acts really doesn't stand up to intense scrutiny.
