The Twenty-sixth Amendment to the United States Constitution provides that a citizen who is 18 years of age older may not be denied the right to vote on account of age, and states:

Section 1.

The right of citizens of the United States, who are 18 years of age or older, to vote, shall not be denied or abridged by the United States or any state on account of age.

Section 2.

The Congress shall have the power to enforce this article by appropriate legislation.

And the Nineteenth Amendment to the United States Constitution provides that a person may not be denied the right to vote on account of sex, and states:

The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of sex.

Congress shall have power to enforce this article by appropriate legislation.

In Iowa, as in all states, the right to vote is protected under federal constitutional amendments. The Twenty-sixth Amendment ensures that citizens who are 18 years of age or older cannot be denied the right to vote based on their age. This means that in Iowa, individuals who meet this age requirement are eligible to vote in all elections, provided they also meet other state-specific voter registration requirements. Additionally, the Nineteenth Amendment guarantees that the right to vote cannot be denied or limited on the basis of sex. This amendment enfranchised women and solidified their right to participate in the electoral process. Iowa adheres to these constitutional protections and cannot enact laws that would infringe upon these federally established voting rights. Both amendments also grant Congress the authority to pass legislation to enforce these rights, ensuring that states like Iowa comply with these constitutional standards.
