daisy_knotwise yesterday that shifting Roberts' nomination to Rehnquist's seat would make sense, since O'Connor has promised to stay on the bench until a successor is confirmed and it would be the best thing for the Court and the country.I hadn't expected him to actually nominate Roberts for Chief Justice, but -- thinking about it -- he's probably the best choice that Bush had available to him, given that the sitting options on the court were Scalia and Thomas. There's some reasonable chance that Roberts is a consensus builder, which is more than can be said for the other two.
