"It will be the office of the President to nominate, and, 
     with the advice and consent of the senate, to appoint. 
     There will, of course, be no exertion of choice on the 
     part of the Senate. They may defeat one choice of the 
     Executive, and oblige him to make another; but they 
     cannot themselves choose — they can only ratify or 
     reject the choice he may have made."
