Political filing is primarily arranged in chronological order with subject divisions within a year reflecting the political activities of the year. A separate sub-series was created for the RH MS 1555 addition. Material in this sub-series was arranged in alphabetial order based on provided folder titles and the general order of the material while kept at the Spencer Research Library.

Election years contain material on the major state races, which includes campaign materials, press releases, and correspondence. Files were kept on presidential candidates and on national political leaders who visited Kansas. Each year's filing also contained information relating to local, state, and national Democratic committees.

This series also contains a wide variety of material relating to Docking's reelection campaigns and includes campaign publications, policy papers, correspondence, and some notes and memos on strategy.
