The Democratic National Convention in Chicago endorses the Johnson administration's platform on the war in Vietnam and chooses Vice President Hubert Humphrey as the party's nominee for president. The decision on the party platform resulted in a contentious three-hour debate inside the convention hall.
Outside, a full-scale riot erupted, where antiwar protesters battled with police and National Guardsmen. By the time the convention was over, 668 demonstrators had been arrested and many Americans were stunned by the images of armed conflict in the streets. Humphrey's Republican opponent, Richard Nixon, very successfully used this incident in a call for return to law and order that won him much support during the election campaign.
