Duncan was responsible for the 1930 introduction and passage of the partial veto into the Wisconsin state constitution, considered "the most extensive" veto power that has been "given to any state executive." He was considered less doctrinaire than Congressman Victor Berger, and at one time was discussed as a potential progressive candidate for Governor of Wisconsin under some form of Progressive/Socialist fusion ticket. He acted as executive secretary to Governor Philip La Follette, and was asserted to have (unsuccessfully) led efforts to lure Socialists into the La Follette camp. He did not seek re-election to the Senate in 1932; Socialist Assemblyman George Hampel was nominated to succeed Duncan in the 6th District, but was defeated by a Democrat in the 1932 Democratic landslide.
