Then you should read these two posts by Kevin Walsh.
In the first post, Kevin explains the way in which Justice Kagan’s dissent lines up in important ways with the views of Judge J. Harvie Wilkinson in his opinion for the Fourth Circuit in Joyner v. Forsyth County (Justice Kagan explicitly relies on some language in Joyner, but the similarities in outlook run deep).
The second post discusses a pending cert. petition–the Elmbrook School District case out of the Seventh Circuit in which Judges Easterbrook, Posner, and Ripple authored dissents from the court’s en banc opinion–and what might happen to it in light of the Court’s holding in Greece.
Both issues are discussed at length in the article that Kevin and I wrote together–Judge Posner, Judge Wilkinson, and Judicial Critique of Constitutional Theory (see in particular Parts I(B) and II(C)). You should read that too!
