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

Citizens must be at least eighteen years old to vote for President. This age requirement is established by the 26th Amendment to the United States Constitution, ratified in 1971. The amendment was significant in broadening the right to vote, particularly during a time when many young Americans were being drafted to serve in the Vietnam War but were not eligible to vote.

As a result of this change, the voting age was lowered from twenty-one to eighteen, ensuring that young adults have a voice in the electoral process that affects their lives and futures. It's a crucial constitutional provision that reflects the principle of democratic participation, granting suffrage to a wider demographic of the population. The other age options do not meet this constitutional requirement, as citizens are not legally permitted to vote until they reach the designated age of eighteen.
