I think the selection of Gonzales to be AG makes it fairly certain that Gonzales will not be nominated to replace Chief Justice Rehnquist should he resign at the end of this term (as seems likely). But I still believe Gonzales remains a potential nominee should Justice Stevens resign, as liberal opposition to a conservative replacement for Stevens will be be greater than it will be for the next Chief. So Gonzales Supreme Court stock is down, but not out (at least not yet).
