Material about the National Farmers Union is also extensive but fragmentary. There is a great deal of material about the Michigan chapter of the NFU between 1933 and 1938, including material dealing with the internal power struggle that eventually led to Graham's ouster. Once he was ousted, however, Graham's files become very weak. Even for the period 1943-1947, when he was working directly for the organization, he seems to have either received or retained few documents. In the 1970s, however, Graham began to save most of the printed material sent to him by the NFU.
