Answer:
Except for North Dakota, the remaining states require the citizens to register for voting before they vote.
Explanation:
- In order to restrict the malpractices that are prevalent during voting, all the states across the United States except North Dakota need their citizens to register as a 'voter' to become eligible for voting.
- In the state of North Dakota, the only requirement that the voters need to fulfill is that of producing an identification proof to prove that they are a resident of North Dakota and are above 18 years of age.
