When did the Socialist Party in the US disband?
Socialist Party of America
Following the election, the governing National Committee of the CPPA met in Washington, D.C. While the body had a mandate from the July convention to issue a call for a convention to organize a new political party, the representatives of the critical railway unions, with the exception of William H. Johnston of the Machinists, were united in opposition to idea. The railroad unions instead proposed a motion not to hold the 1925 organizational convention. This proposal was defeated by a vote of 30 to 13. Following their defeat on this question, the railroaders on National Committee members withdrew from the meeting, announcing that they would await further instructions from their respective organizations with regards to future participation.[33] The loss of the very unions who had brought about the CPPA spelled its demise.
