The Socialist Party of America also held their convention in Cleveland in 1936. In a rift that led to many right wing party members to form the Socialist Democratic Federation, left-leaning forces took control and roundly condemned organized labor's endorsement of FDR.
Key speakers included Norman Thomas, Leo Krzycki, national party chairman and Milwaukee Mayor Daniel Hoan.
This is to repeat the mistake of 1916 when labor supported Wilson because 'he kept us out of war.' It is to repeat the mistake of the German Social Democrats who voted for Hindenberg because they did not want Hitler. - Norman Thomas
Roosevelt proposes to patch up capitalism without attempting to reach the roots of our economic ills. He has no wish to abolish it and until it is abolished we cannot hope for any fundamental improvement in conditions. - Mayor Hoan
