The Twenty-sixth Amendment that enfranchised 18-to-20-year -olds led to reduction in the national voter turnout rate.
The Twenty-sixth Amendment to the Constitution of the United States extended voting rights to citizens between the ages of 18 and 20. Earlier, the voting age was set at 21 and above.
The call to reduce the voting age became particularly salient after the Vietnam War. Young men between the age of 18 and 21 were drafted into the armed forces or to support military operations. After the war, proponents of extending voting rights coined the slogan “old enough to fight, old enough to vote”.
The result of lowering the voting age was that the national voter turnout rate declined.
