Worth every penny you’ve paid for them: 1) Roberts will vote with Scalia and Thomas on the parental-notification case and a future partial-birth abortion case. 2) Roberts will decline to join Scalia and Thomas in calling for the overturn of Roe and Casey. 3) Pundits will infer that this move by Roberts means that he is a vote for Roe/Casey. 4) This assumption, by making Roe/Casey look safe, will make it easier to confirm another conservative justice (should a third vacancy arise on Bush’s watch). 5) This assumption will be incorrect.
