Former child star Shirley Temple Black, who has served Republican administrations in several diplomatic posts, says she wants to be head of the U.S. Information Agency if George Bush is elected president. The one-time darling of Depression-era movie fans auditioned for the part on a television interview broadcast Thursday, saying her years in films and government have prepared her to run the United States' main voice abroad. "I haven't told George Bush this yet, I should tell him before I tell you. But I would like to be the director of the United States Information Agency," Black said in a taped appearance on the CBS News "Nightwatch" program.
