During the Dust Bowl period, Guthrie joined the thousands of Okies who were migrating to California looking for work, leaving his wife and children in Texas. Many of his songs are concerned with the conditions faced by these working-class people.  During the late part of that decade, he achieved fame with radio partner Maxine "Lefty Lou" Crissman as a broadcast performer of commercial hillbilly music and traditional folk music. Guthrie was making enough money to send for his family, who were still living in Texas. While appearing on the commercial radio station KFVD, owned by a populist-minded New Deal Democrat, Frank W. Burke, Guthrie began to write and perform some of the protest songs that would eventually appear on Dust Bowl Ballads.  While at KFVD, Guthrie met newscaster Ed Robbin. Robbin was impressed with a song Guthrie wrote about political activist Thomas Mooney, believed by many to be wrongly convicted in a case that was a cause celebre of the time. Robbin, who became Guthrie's political mentor, introduced Guthrie to socialists and Communists in Southern California, including Will Geer (who, in turn, introduced Guthrie to John Steinbeck). Robbin remained Guthrie's lifelong friend, and helped Guthrie book benefit performances in the Communist circles in Southern California. Notwithstanding Guthrie's later claim that "the best thing that I did in 1936 was to sign up with the Communist Party", he was never a member of the party. He was noted as a fellow traveler--an outsider who agreed with the platform of the party while not subject to party discipline. Guthrie wrote a column for the Communist newspaper, People's World. The column, titled "Woody Sez", appeared a total of 174 times from May 1939 to January 1940. "Woody Sez" was not explicitly political, but was about current events as observed by Guthrie. He wrote the columns in an exaggerated hillbilly dialect and usually included a small comic; they were published as a collection after Guthrie's death. Steve Earle said of Guthrie, "I don't think of Woody Guthrie as a political writer. He was a writer who lived in very political times."  With the outbreak of World War II and the non-aggression pact the Soviet Union had signed with Germany in 1939, the owners of KFVD radio did not want its staff "spinning apologia" for the Soviet Union. Both Robbin and Guthrie left the station. Without the daily radio show, his prospects for employment diminished, and Guthrie and his family returned to Pampa, Texas. Although Mary Guthrie was happy to return to Texas, Guthrie preferred to accept Will Geer's invitation to New York City and headed east.
