Legislature Zimmerman was elected to the
Wisconsin State Assembly by six votes in 1908 in a three-way race, receiving 1703 votes on the Republican ticket to 1697 for
Democrat Harry R. McLogan, and 1159 for
Socialist Gilbert H. Poor, to represent the 8th
Milwaukee County district (8th and 23d
wards of the City of Milwaukee). He was an active member of the Progressive faction of his party, but served only one term (1909–1910), losing the 1910 election in a four-way contest to Socialist
James H. Vint with 1521 votes, to 1501 for Zimmerman, 143 for McLogan, and 12 for
Prohibitionist William H. Trout.
Secretary of State In 1922, Zimmerman (by then an
industrial relations manager for
Nash Motors) had moved to the
Town of Lake and served two years on the Town Board. He received the Republican nomination and election as Wisconsin Secretary of State in 1922 (with 77.7% of the vote in a four-way race) and re-election in 1924 in a five-way race, earning a then-record 509,771 votes statewide. During this period he remained closely identified with the Progressive faction of the Republican Party.
Governor When the Progressives refused to endorse him in the
gubernatorial election in 1926 (because of his failure to support the
1924 presidential candidacy of
Robert M. La Follette Sr.), Zimmerman ran in the Republican
primary election as an "independent" against both Progressive (
Herman Ekern) and Stalwart (
Charles B. Perry) candidates, as well as another "independent". Zimmerman won the Republican nomination and was elected by an absolute majority, outpolling Perry (who came in second, running as an independent), as well as the Democratic, Socialist, Prohibitionist and
Socialist Labor candidates combined, with 350,927 votes out of 552,921. In 1928 he was defeated for re-nomination, running a poor third to Stalwart
Walter J. Kohler Sr., and Progressive Congressman
Joseph D. Beck. Thereafter he went into a political decline for several years, briefly holding a position in the Beverage Tax Commission in 1936.
Secretary of State once more Zimmerman was nominated and elected Secretary of State on the Republican ticket in 1938 and served until his death, polling a larger vote at each subsequent election and in 1952 again received the highest total ever given any candidate for any office in the state. == Private life ==
