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

Citizens must be at least 18 years old to vote in presidential elections, which aligns with the requirements established by the 26th Amendment to the United States Constitution. This amendment was ratified in 1971 and lowered the voting age from 21 to 18, reflecting a societal consensus that younger individuals should be allowed to participate in the electoral process, especially considering that they can be drafted for military service at that age.

The option indicating "25" is not related to voting eligibility for federal elections. While some states may have different regulations regarding candidates' ages, the minimum voting age is firmly set at 18 nationwide for all federal elections, including presidential elections. Understanding this age requirement is crucial for recognizing the rights of citizenship and the importance of participation in democracy.
