After long activity in
Marathon County politics, and election to the Wisconsin Socialist Party
executive committee, Marth was first elected to the State Assembly's second Marathon County district by a three-to-one margin in a
special election in January 1918 to succeed
Republican D. S. Burnett (who had resigned to enter military service). At the November
general election he was re-elected, with 1883 votes to 1313 for Republican Fred Paulus, 1203 for
Democrat George Merisette, and 40 for independent F. A. Wilcox. He served on the Committee on Taxation. In 1920, after narrowly losing a hard-fought race for mayor of Wausau by 246 votes in September, Marth was defeated for re-election to the Assembly by Republican
Lewis H. Cook, who received 5084 votes, to 3204 for Marth and 1100 for Democrat Kurt Beyreis. He continued to serve on the executive committee of the Wisconsin Socialist Party until 1935, and remained an outspoken Socialist his whole life. In 1946, he was the Socialist nominee for
Wisconsin's 25th State Senate district (
Lincoln and Marathon counties); he came third, with 601 votes to 16,859 for Republican
Clifford "Tiny" Krueger and 7,827
write-in votes for the incumbent, Republican
William McNeight, who had lost to Krueger in the
primary election. == Personal life ==
