Vietnam Era Efforts
The war in Vietnam and the return of the draft brought the issue to the forefront again. In 1969, no fewer than 60 resolutions were introduced in Congress to lower the minimum voting age, but none resulted in any action. Finally, in 1970 Congress passed a bill extending and amending the Voting Rights Act of 1965, which contained a provision that lowered the voting age to 18 in federal, state and local elections.
Enacting the Amendment
By the following year, there was enough support in Congress to pass the 26th Amendment that officially lowered the voting age to 18. On March 10, 1971, the U.S. Senate voted unanimously in favor of the proposed amendment. It was ratified by the necessary majority of 38 states, and signed into law by President Richard Nixon.
