I believe you are mistaken. I am pretty sure Bush has used it to appoint at least one judge. Someone correct me if I am wrong.
You're corrected - sorry you are wrong - as indicated by the number of Circuit Court Judges that were (and are) being fillibustered in the Senate - i.e. Brent Kavanaugh - currently still stuck in the Senate vortex awaiting confirmation to the DC Court of Appeals.
