This issue brief from The Brennan Center contains sample legislative language for the main components of a fully modernized voter registration system: (1) one-stop automated registration of eligible citizens who interact with other government agencies; (2) permanent voter registration, so that once a voter is registered, she stays registered regardless of whether she moves within the state; (3) an online interface to check and update registration information; and (4) fail-safe provisions so that voters can correct errors or omissions on the voter rolls up through Election Day.
