persuade an uninterested populace to support the war and the draft, George Creel, a veteran of the newspaper industry, became the United States' official war propagandist. He set up the Committee on Public Information, which recruited 75,000 speakers, who made 750,000 four-minute speeches in 5,000 cities and towns across America. Creel later helped form the American Alliance for Labor and Democracy, with union leader Samuel Gompers as president, to win working-class support for the war and "unify sentiment in the nation". The AALD had branches in 164 cities, and many labor leaders went along although "rank-and-file working class support for the war remained lukewarm ...", and the campaign was ultimately unsuccessful.

Effects By the guidelines set down by the Selective Service Act, all males aged 21 to 30 were required to register to potentially be selected for military service. At the request of the War Department, Congress amended the law in August 1918 to expand the age range to include all men 18 to 45, and to bar further volunteering. By the end of World War I, some two million men volunteered for various branches of the armed services, and some 2.8 million had been drafted. This meant that more than half of the almost 4.8 million Americans who served in the armed forces were drafted. Due to the effort to incite a patriotic attitude, the World War I draft had a high success rate, with fewer than 350,000 men "dodging" the draft. Differences from previous drafts The most important difference between the draft established by the Selective Service Act of 1917 and the Civil War draft was that substitutes were not allowed. During the Civil War, a drafted man could avoid service by hiring another man to serve in his place. A mostly inaccurate perception spread that substitutes were used primarily by wealthy men and was resented by those who could not afford them or considered them dishonorable. The practice of substitutes was prohibited in Section Three of the Selective Service Act of 1917: No person liable to military service shall hereafter be permitted or allowed to furnish a substitute for such service; nor shall any substitute be received, enlisted, or enrolled in the military service of the United States; and no such person shall be permitted to escape such service or to be discharged therefrom prior to
