Question

Before the 26th Amendment, many Americans could not vote until the age of 21. Why did supporters of this amendment believe that Americans should have the right to vote no later than age 18?

Answer 1

From what I know, they were upset that men were denied the right to vote, yet in WWII and Vietnam they were being conscripted to join the Army. 'Old enough to fight, Old enough to vote.'

Answer 2

Efforts to change the legal voting age became more popular after World War II. The federal government’s draft sent young soldiers to war and military service when they were 18 years old. During World War II, most American males between the ages of 18 and 21 spent time serving in the armed forces, but they did not have the right to vote. Supporters of a constitutional amendment argued that citizens who were old enough to fight for their country should be old enough to have voting rights. These arguments won support from Americans and their leaders, leading to the passage of the 26th Amendment.
