How old do citizens have to be to vote for President?

In the United States, citizens must be at least eighteen years old to vote for President. This age requirement is established by the 26th Amendment to the U.S. Constitution, which was ratified in 1971. The Amendment was enacted to ensure that young adults, particularly those who were eligible to be drafted into military service, also had the right to participate in the electoral process.

This means that only individuals who have reached the age of eighteen can legally cast their ballots in presidential elections, reflecting the country's commitment to allowing young adults to have a say in their governance and the future of the nation. The other options do not align with this constitutional requirement, as sixteen, nineteen, and twenty-one years old do not meet the legal age established for voting in federal elections.
