These stories that the Chief Justice behaved politically in upholding the constitutionality of the Affordable Care Act - - and thus somehow behaved inappropriately - - are really naive.
From an advisory committee in the smallest Village and Town in the county to the US Supreme Court, all decisions are political, because people, not robots, are making the decisions.
"Political" is not the same thing as "partisan," or "prejudicial."
I can remember David Fellman, my Civil Liberties professor at UW-Madison a long time ago saying to the class, "Supreme Court Justices read the newspapers, too."
