North Dakota is the only state that does not require voters to register. You just show up with ID and vote. Plaintiffs: A 2017 change to the law disenfranchises roughly 10% of the state’s eligible Native American voters, many of whom lack residential street addresses and thus can’t get the requisite ID. Eighth Circuit: The law is not a substantial burden to the vast majority of eligible voters, and it’s not clear how many would-be voters tried to obtain ID and were unable to. Dissent: The law was purportedly enacted to address voter fraud, but there is no evidence of voter fraud.
