Automatic voter registration map: Find out if your state has it and how effective it is

The National Voter Registration Act established voter registration services at state motor vehicle agencies, coining the term the “Motor Voter” law. Since its passage, at least 24 states and Washington, D.C., have implemented automatic voter registration systems. This method automatically registers eligible citizens who interact with their local driver’s licensing department, unless they decline, according to the MIT Election Data and Science Lab.
