Tennessee passes a “durational residency” rule for citizens to qualify to vote. Under this rule, voters must live in the state for one year and in the county for ninety days before being allowed to vote. In Dunn v. Blumstein, the U.S. Supreme Court strikes down the residency rule as an unconstitutional restriction on the right to vote. The Court notes that there are other ways to achieve the state’s goals of deterring voter fraud and ensuring that voters are knowledgeable without blocking otherwise eligible voters from participating in elections.
