At what age are U.S. citizens eligible to vote in federal elections?

• A. 16 years old
• B. 18 years old
• C. 21 years old
• D. 25 years old

Answer: (B)

U.S. citizens are eligible to vote in federal elections at the age of 18. This voting age is established by the 26th Amendment to the Constitution, which was ratified in 1971. The amendment was enacted in response to a growing movement that argued that if individuals were old enough to be drafted into military service at 18 years old, they should also have the right to participate in the electoral process. This principle underscores the importance of civic engagement and acknowledges that young adults should have a voice in decisions that affect their lives and futures. Thus, age 18 is significant as it marks the establishment of a fundamental right to vote in the democratic system of the United States.
