Which groups are granted the right to vote through constitutional amendments?

The correct answer includes both women and African Americans, reflecting two significant amendments that expanded voting rights in the United States, as well as the broader sweep of all citizens over age 18, which was established by the 26th Amendment.

To begin with, the 19th Amendment granted women the right to vote in 1920, which represented a landmark change in acknowledging women's suffrage. The 15th Amendment, passed in 1870, prohibits the denial of the right to vote based on race, color, or previous condition of servitude, thereby extending voting rights to African American men, although many still faced barriers even after its ratification.

The 26th Amendment, ratified in 1971, further extended voting rights to all citizens who are 18 years of age or older, ensuring that younger adults could participate in the electoral process. This development was significant during a time when young Americans were actively engaging in political movements, particularly during the Vietnam War.

Therefore, the inclusion of both groups and the age specification encompasses the essential evolution of voting rights in the United States, accurately capturing the amendments that expanded accessibility and representation in the electoral system.
