Constance Myers indicates that three factors led to the expulsion of the Trotskyists from the Socialist Party in 1937: the divergence between the official Socialists and the Trotskyist faction on the issues, the determination of Jack Altman's wing of the Militants to oust the Trotskyists and Trotsky's own decision to move towards a break with the party. Recognizing that the Clarity faction had chosen to stand with the Altmanites and the Thomas group, Trotsky recommended that the Appeal group focus on disagreements over Spain to provoke a split. At the same time, Thomas, freshly returned from Spain, had come to the conclusion that the Trotskyists had joined the Socialist Party not to make it stronger, but to capture the organization for their own purposes. The 1,000 or so Trotskyists who had entered the Socialist Party in 1936 exited in the summer of 1937 with their ranks swelled by another 1,000.
