This isn't about Bush's right to name "his" justice. This isn't about my right to participate in a formerly conservative forum for discussion. This is about the future of the court and the future of the country.
Sorry to wake you.
Elevating an Associate Justice to be Chief Justice is rare, having happened only three times. The usual practice is to appoint as Chief Justice a person not already on the Court. So, in no sense was Scalia "passed over".
