Which state does not require voter registration?

North Dakota is the only state that does not require voter registration, distinguishing it from the other states listed. This unique approach allows residents to vote without the burden of registering in advance, which is often mandated in other states. The rationale behind North Dakota's system is to promote higher voter participation by simplifying the voting process.

In contrast, Texas, California, and Florida all have formal voter registration requirements, which necessitate that individuals register ahead of Election Day to be eligible to vote. Each of these states has its own specific regulations and deadlines for voter registration, and failure to adhere to these can result in a loss of voting rights for that election cycle.
