The United States needs a new ambassador to the Vatican. Professor Miguel Diaz has returned to the U.S. and will be teaching at Dayton.In the NCR report on the matter, John Allen mentioned as possible nominees: Stephen Schneck of Catholic U and Nicholas Cafardi of Duquesne (he is a civil and canon lawyer). Good suggestions, but how about Bart Stupak (retired congressmen from Michigan who saved Obamacare from oblivion), or Sister Simone Campbell (of Nuns on the Bus and other events!)?Who would you nominate?
