What methods did government use to counter the loss of enthusiasm and opposition to World War I at home?

Jeanette Keith wrote a great book on this subject it is called “Rich Man’s War, Poor Man’s Fight.”  The Wilson administration was so concerned about opposition to U.S. entry into the raging European conflict that it pushed through Congress the Espionage and Sedition Acts, which were vigorously used against people who spoke out against the war. Neither the effusive pro-war rhetoric of Wilson and his allies nor the crackdown on civil liberties was, however, able to extinguish the sentiment among many Americans that the war was a horrible blunder.  “Within days of its enactment, a barber in Roanoke, Virginia, was arrested by federal agents for having distributed a flyer entitled “A Rich Man’s War and a Poor Man’s Fight.” Freedom of speech was unimportant to Wilson and his backers. Maximizing the war effort trumped every other consideration, including the Constitution.”
