Which amendment to the United States Constitution ensures the right to vote for citizens aged 18 and older?

The 26th Amendment to the United States Constitution establishes the right to vote for citizens aged 18 and older. Ratified in 1971, this amendment emerged during a time of significant social and political change, particularly related to the Vietnam War. Many argued that if individuals were old enough to be drafted into military service at the age of 18, they should also be granted the right to participate in electing their leaders. As a result, the amendment was a response to the demand for greater youth representation in the democratic process.

In contrast, the other amendments listed address different aspects of voting rights and suffrage. The 24th Amendment prohibits poll taxes in federal elections, while the 22nd Amendment limits the president to two terms. The 19th Amendment grants women the right to vote. Understanding the distinct purposes of each amendment highlights the importance of the 26th Amendment in advancing voting rights for younger citizens.
