This comment needs to be better supported. It is intuitive that votes for POTUS would be a federal matter, and Wikipedia does not mention a jurisdictional issue for that case, nor any other federal interference conflict whatsoever.
Also, singling out Scalia when four other justices voted with him is biased. It is also an incredible stretch to cast responsibility for an incompetence in handling an unanticipated war on any individual (especially in the judiciary!).
