“Thirty-six states have laws requesting or requiring voters to show some form of identification at the polls. The remaining 14 states and Washington, D.C., use other methods to verify the identity of voters. Most frequently, other identifying information provided at the polling place, such as a signature, is checked against information on file. Proponents argue increasing identification requirements can prevent in-person voter impersonation and increase public confidence in the election process. Opponents say there is little fraud of this kind, that the burden on voters unduly restricts the right to vote and that the laws impose unnecessary costs and administrative burdens on elections officials. All voters, regardless of the type of verification required by the states, are subject to perjury charges if they vote under false pretenses.”
