Wilson was renominated at the 1916 Democratic National Convention without opposition. In an effort to win progressive voters, Wilson called for legislation providing for an eight-hour day and six-day workweek, health and safety measures, the prohibition of child labor, and safeguards for female workers. He also favored a minimum wage for all work performed by and for the federal government. The Democrats also campaigned on the slogan "He Kept Us Out of War," and warned that a Republican victory would mean war with Germany. Hoping to reunify the progressive and conservative wings of the party, the 1916 Republican National Convention nominated Supreme Court Justice Charles Evans Hughes for president; as a justice he had been totally out of politics in 1912. Though Republicans attacked Wilson's foreign policy on various grounds, domestic affairs generally dominated the campaign. Republicans campaigned against Wilson's New Freedom policies, especially tariff reduction, the new income taxes, and the Adamson Act, which they derided as "class legislation."
