Ben Rubin (December 20, 1886 – February 24, 1942) was a cigar maker, zookeeper, union activist and member of the Wisconsin State Assembly from Milwaukee who served four terms.

[1] Rubin's district had the largest concentration of African-Americans in Wisconsin, and he was the author of a number of civil rights bills on topics such as insurance,[2] employment by regulated utilities, and public accommodations.

This time Kaiser (with Franklin D. Roosevelt at the top of the Democratic ticket) was the victor, with 2240 votes to Rubin's 2130, Cord's 1412, and another 129 for the two independents.

[6] The final official count was 1289 for Kaiser (Democrat), 1262 for Rubin (Socialist), 1002 for Fred G. Miller (Progressive), 638 for Frederick G. Peterson (Republican), and 49 for an independent and "scattering".

[7] In 1936 (at which time he was serving his fourth term on the executive board of the Milwaukee Federated Trades Council, Rubin again faced Kaiser in the general election, this time nominally as a Progressive (there were no official "Socialist" candidates during this era of Progressive/Socialist "federation" tickets, and no Socialist primary[8]).
