Duffy acted as city editor of the Grand Forks Herald in 1913, before opening a law firm with Torger Sinness in Minnewaukan, North Dakota. He married Exzelia Beauchamp in Fargo on September 11, 1915. The couple had two daughters: Margaret and Patricia.
Sinness and Duffy moved their law firm to Devils Lake in 1925.

Duffy also acted as Code Commissioner from 1939-1944, and as the City Attorney for Devils Lake for many years.
Duffy was an active member of the Republican party, and served as precinct committee, chair of the Ramsey County Republican Committee, and member of the state Republican Central Committee. He was also a representative to the 1936 Republican National Convention in Cleveland. He was elected to the North Dakota Senate in 1948, serving until 1956.

The Clyde Duffy Papers date from 1911-1973, and consist mainly of correspondence. Duffy was an active member of the North Dakota Republican Party, and this is reflected in the large amount of political correspondence in the collection. Also included is correspondence, reports, and legal materials related to his service as a Special Investigator appointed by Governor John Moses. Other materials include several folders containing the text of his speeches, legal materials, and a 1973 autobiography entitled “Observations Along the Way.”
The collection was reprocessed in January 2005; material housed in Boxes 5 and 6 was rearranged and placed into acid-free folders. Researchers should note that some material which was listed as being housed in these two boxes was not found when the collection was reprocessed. The material in question consisted mainly of various political pamphlets collected by Duffy.
Several publications were separated and added to the North Dakota Book Collection. This includes four editions of The Red Flame, as well as several publications of the United States Senate Committee on Privileges and Elections. From 1941 and 1942, this committee investigated claims the Langer was not entitled to his Senate seat due to misconduct “as a public officer and as an attorney at law.” The committee ultimately recommended that Langer should not be seated, although the entire Senate voted 52-30 to seat Langer.
