Section 1. The right of citizens of the United States, who are eighteen years of age or older, to vote shall not be denied or abridged by the United States or by any State on account of age.
Section 2. The Congress shall have power to enforce this article by appropriate legislation.
What does this mean??
The 26th amendment changed the voting age from 21 years old to 18 years old. At the time this was happening we were at war with Vietnam. People were outraged that our 18 year olds were fighting in the war but could not even vote.
Why this picture?
This is a 1969 New Jersey campaign poster supporting the 26th amendment to lower the voting age to 18 from 21.
