It is estimated that between one-quarter and one-third of all Americans eligible to vote are not registered to participate in elections—which is why the Brennan Center for Justice is calling for a radical change in the way voters are signed up. In its new report, Expanding Democracy: Voter Registration Around the World, the center advocates for removing the burden of voter registration from citizens and requiring local governments to automatically add people to voter rolls as soon as they turn 18 years old or become U.S. citizens. Calling the current method “costly, inefficient, and insufficiently accurate,” the report’s authors write that “the registration system is as much a problem for the dedicated civil servants who administer our elections as it is for voters.”
