What do all states currently require in order to vote?

In order to vote in elections, all states require individuals to be citizens of both the United States and the specific state in which they intend to vote. This requirement upholds the principle that voting is a fundamental right reserved for citizens, ensuring that only those with a legal claim to the rights and responsibilities of citizenship participate in the democratic process.

While residency and registration are also important aspects of the voting process, they are not uniform requirements across all states in the same way that citizenship is. Some states have different registration processes, and residency requirements can vary based on factors like how long a person has lived in a state or county. Additionally, membership in a political party is not a requirement for voting in many states, as non-party affiliated individuals can often vote in primary elections or general elections depending on state laws. Thus, citizenship stands out as a universal prerequisite for voting across all states.
