Storey was a long-time classical liberal and Grover Cleveland Democrat who advocated laissez-faire free markets, the gold standard, and anti-imperialism. Storey consistently and aggressively championed civil rights, not only for blacks but also for Native Americans and immigrants (he opposed immigration restrictions). Du Bois continued to play a pivotal leadership role in the organization, serving as editor of the association's magazine, The Crisis, which had a circulation of more than 30,000. The Crisis was used both for news reporting and for publishing African-American poetry and literature. During the organization's campaigns against lynching, Du Bois encouraged the writing and performance of plays and other expressive literature about this issue. The Jewish community contributed greatly to the NAACP's founding and continued financing. Jewish historian Howard Sachar writes in his book A History of Jews in America that "In 1914, Professor Emeritus Joel Spingarn of Columbia University became chairman of the NAACP and recruited for its board such Jewish leaders as Jacob Schiff, Jacob Billikopf, and Rabbi Stephen Wise." Jim Crow and disenfranchisement In its early years, the NAACP was based in New York City. It concentrated on litigation in efforts to overturn disenfranchisement of blacks, which had been established in every southern state by 1908, excluding most from the political system, and the Jim Crow statutes that legalized racial segregation. In 1913, the NAACP organized opposition to President Woodrow Wilson's introduction of racial segregation into federal government policy, workplaces, and hiring. African-American women's clubs were among the organizations that protested Wilson's changes, but the administration did not alter its assuagement of Southern cabinet members and the Southern bloc in Congress. By 1914, the group had 6,000 members and 50 branches. It was influential in winning the right of African Americans to serve as military officers in World War I. Six hundred African-American officers were commissioned and 700,000 men registered for the draft. The following year, the NAACP organized a nationwide protest, with marches in numerous cities, against D. W. Griffith's silent movie The Birth of a Nation, a film that glamorized the Ku Klux Klan. As a result, several cities refused to allow the film to open. The NAACP began to lead lawsuits targeting disfranchisement and racial segregation early in its history. It played a significant part in the challenge of Guinn v. United States (1915) to Oklahoma's discriminatory grandfather clause, which effectively disenfranchised most black citizens while exempting many whites from
