Harry Truman--""man of the people""--in a gently shaded, down home treatment (""I'll do my darndest""). Quibblers might want to challenge some of the sweeping statements here: ""He made many friends for the United States in the world"" (no mention of enemies); ""Today Americans of different colors and sex have equal rights by law."" . . . But the real question is whether any president should be turned into an easy reading hero. Especially when Faber's Harry Truman (1973) allows room for a smidgen of debate.
