The Socialist Party’s state and local candidate lists for the elections of 1910. That spring the party had won a majority and the mayorship in Milwaukee and were seeking to use that victory for the mid-term elections in the fall.

The Socialist Party Official Bulletin. Vol. 7 No. 1. September, 1910.

For a variety of reasons, the national Socialist Party of America did not have an official publication until May 1904 when the national convention mandated the monthly Socialist Party Official Bulletin as a way for the Party to communicate to its members. The name was changed to Socialist Party Monthly Bulletin in October 1911. The Party Builder became the name in 1913 and also became a subscription paper and a weekly. In 1914 the Socialist Party replaced The Party Builder with a regular propaganda newspaper, The American Socialist. These Party paper contain National Committee and National Executive Committee minutes, National Secretary reports, membership figures, financial statements, letters from party members, articles by prominent party leaders, and the figures for election of party officers and internal questions.
