Dasher - that was his Secret Service code name when he ran for President - and the facts of his life are well known: schoolboy, naval officer, peanut farmer, defeated candidate, Governor, President. He's spoken millions of words to us citizens of the United States, and lots of us still wonder who he is. James Wooten has known him for a long time - as Atlanta bureau chief, as campaign correspondent, and now as White House Correspondent for The New York Times. He's talked to Dasher, to his mother, Miss Lillian, his sister Gloria, his brother Billy, and to a lot of other people around the country and in the White House, so by now he's not fooled by words - or by politics either. DASHER: THE ROOTS AND THE RISING OF JIMMY CARTER gets down to the man behind the face - at last.
