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

To vote for President in the United States, citizens must be at least 18 years old. This age requirement is established by the 26th Amendment to the U.S. Constitution, ratified in 1971. The amendment was a significant step in expanding voting rights, particularly influenced by the arguments that if individuals are old enough to be drafted for military service, they should also be allowed to vote.

This requirement reflects a societal consensus on the maturity and responsibility expected of a voter, acknowledging that at 18, individuals are typically nearing adulthood and possess more developed decision-making capabilities. The age of 21 used to be more common for voting eligibility, but the shift to 18 years for federal and state elections represents a more inclusive approach to democratic participation.
