The momentum to lower the voting age came with the military draft held during the Vietnam War. The draft conscripted young people older than 18 into the armed forces. The general feeling of the population was that if young people were joining the war, they deserved to have a say in government. A famous slogan that summarized this view was: "old enough to fight, old enough to vote."
