The decision to nominate John Roberts for Chief Justice is no more a cause for delay than Katrina. Roberts is the same nominee as he was when picked to replace Justice O’Connor. There are no additional documents, decisions, or other matters that need to be considered. In short, nothing has changed other than the politics — and this is the only reason Democrats are calling for a delay. Senate Democrats agreed to this schedule weeks ago. Chairman Specter should hold them to their agreement.
