Zueblin lectured extensively and contributed frequently to philosophical and sociological journals, and to many of the most prominent magazines and reviews.
He was a strong advocate of the commission plan of government and believed every city would eventually adopt the system.
In a 1911 interview to The Kansas City Star, Zueblin predicted the system would eventually replace the United States Senate and House of Representatives.
During this time, in addition to his extensive lecturing career, he was put forward by the Progressive Party as a candidate for the Massachusetts Senate (1912).
Zueblin died from a brain hemorrhage while staying in Corsier-Geneva, Switzerland on September 15, 1924.
