The 23 labor unions that sent a delegate with instructions to install them, had a total membership of 51,430. The total membership of the other 20 organizations was 91,500; this means that about one third of the membership represented at the convention held almost the entire voting power. Of the over 51,000 votes aggregated by those organizations prepared to install, 48,000 were distributed among five organizations: the Western Federation of Miners (27,000 members), American Labor Union (16,750 members), United Metal Workers (3,000 members), United Brotherhood of Railway Employees (2,087 members), and the Socialist Trade and Labor Alliance (1,450 members). Only a few organizations thus held almost all the power at the convention. The first two labor unions listed above outnumbered all others ten to one.
