Elsewhere, the 1912 platform of the Tennessee party stated that white supremacist ideology was a tool of the capitalist class to divide and rule the working class, while the Virginia party passed a resolution three years earlier to focus more attention on encouraging solidarity between black and white workers and to invite non-white workers to join the party. Most notable was the Socialist Party of Oklahoma, which led opposition to the state's 1910 ballot initiative on a grandfather clause to prevent blacks from voting. Prominent party member Oscar Ameringer wrote the ballot argument against it, and the party launched an unsuccessful lawsuit to prevent the question from going to the ballot. Party propaganda argued that if working-class solidarity did not extend across racial lines, then blacks would be exploited as strikebreakers and as an instrument or repression by the ruling class. The state party's 1912 platform stated that "safety and advancement of the working class depends upon its solidarity and class consciousness. Those who would engender or foster race hatred or animosity between the white and black sections of the working class are the enemies of both." This stance earned the party support from key black leaders in the state.
