Which of the following is a qualification for voter registration in Delaware?

In Delaware, one of the primary qualifications for voter registration is that individuals must be U.S. citizens. This requirement ensures that only those who have the legal right to participate in federal elections can vote, reinforcing the foundational democratic principle that voting is a right reserved for citizens.

The stipulation that voters must be U.S. citizens serves to maintain the integrity of the electoral process and to uphold the laws surrounding citizenship and voting. Additionally, this aligns with the overall requirements set forth in other states, which also mandate citizenship as a prerequisite for voter participation.

Understanding this helps to clarify the importance of citizenship in the electoral system, while the other options present requirements that do not align with voter registration criteria in Delaware. For instance, while age is a factor (individuals must be at least 18 years old to vote), being at least 21 is not a requirement for voter registration. Likewise, holding a driver's license is not a prerequisite for voting, as individuals can register and vote without one. Lastly, residency in New Jersey is irrelevant when discussing qualifications for voting in Delaware, as states have their own specific residency requirements.
