Dear Associated Press,
O'Connor is not the "swing vote" in every case in which she's in the 5-4 majority. In today's rulings regarding the Ten Commandments, Justice Breyer is much more accurately characterized as the "swing," as he voted with the majority both to permit the Texas monument but to disallow the Kentucky display. O'Connor, in contrast, consistently opposed both exhibitions of the Commandments, and wrote a dissent in the Texas case to boot.

Sean notes that "it shows the bias of the media to promote or tear-down particular judges. This in turn keeps the laymen from having any 'true' grasp on legal theory." O'Connor as swing-vote is the prepared script for 5-4 cases -- Kennedy also, of late -- so perhaps liberals now can start bitching about being betrayed by Breyer. I hate getting left out of the things conservatives get to do!

And it turns out that the SCOTUS blog miscalled it, aside from O'Connor's writing separately -- the aforementioned dissent plus a concurrence in McCreary.
UPDATE: Will Baude makes the same point.
