The U.S. presidential election in 1916 pitted incumbent president Woodrow Wilson against Supreme Court Justice Charles Evans Hughes.
While Wilson was in office, conflict erupted in Europe to become what would be World War I. Although Americans generally supported Allied powers, voters wanted the United States to remain out of the conflict. To capitalize on public opinion on this issue, Wilson campaigned on the slogan, "He kept us out of war."
Months after winning reelection, Wilson went to Congress to approve a declaration of war with Germany and its allies. Wilson have campaigned on the implicit promise American neutrality in World War I, but he never explicitly stated he would never lead the United States to join the war.
