Dug a little deeper: seems Afroyim v. Rusk http://en.wikipedia.org/wiki/Afroyim_v._Rusk says something different about the average citizen. There was an amendment that did not get ratified ( http://www.heraldica.org/topics/usa/usnob.htm and http://en.wikipedia.org/wiki/Titles_of_Nobility_Amendment ). I remember Ike's knighthood was honorary, but he was elected President.
