What is the main provision of the 26th Amendment?

The main provision of the 26th Amendment is significant because it lowers the voting age from 21 to 18 years old. This change was largely influenced by the argument that if individuals are old enough to be drafted for military service, they should also have the right to vote. This amendment ensures that younger citizens can fully participate in the democratic process, reflecting the idea that age should not be a barrier to exercising one's right to vote. The ratification of the 26th Amendment in 1971 was a pivotal moment in expanding voting rights, particularly in light of the social movements occurring during that era which advocated for a more inclusive and representative democracy.
