John Kastle of the People's Party had previously served as president of the Chamber of Commerce. A.E. Cochran had been active in Democratic Party.
Independent candidate William H. Carlson campaigned vigorously, making numerous extravagant campaign promises, including electric car lines on every street, luxury hotels, steamship lines to every port on earth, transcontinental railroads, and jobs with high wages for all.
