 In the South, the Southern Tenant Farmers Union (STFU), which Communist UCAPAWA President Donald Henderson regarded as "a utopian agrarian movement," became affiliated with the union.A power struggle between the groups erupted soon after the affiliation and culminated with a 1939 protest against the eviction of sharecroppers in Missouri, which was not supported by the national organization.As a result, the STFU left the union.
