The latest analysis of the benefits of same-day registration comes from The Hill by Brian Miller and Miles Rapoport:

New Census data suggests an estimated 3.6 million voters did not cast a ballot in the 2018 midterm election because of a problem with their voter registration. To have so many Americans unable to vote because of an inefficient and unnecessary layer of bureaucracy is shameful. The good news is this is a solvable problem, and many states are taking positive action.

Same-day registration, a policy spreading in states across the nation, allows eligible voters to register or fix a problem with their registration when they go to the polls to vote. Last month, New Mexico became the 20th state to enact the policy, and more states are considering it, with legislation pending in Arizona, Delaware, Georgia, Pennsylvania, Tennessee, and Indiana. The policy’s effectiveness at boosting turnout is clear. 

See the full story here. Vermont today is the state with the highest voter registration rates. Coming from the secretary of state’s office last year, a report was released showing there were 481,111 registered citizens in Vermont. This comprises about 92.5 percent of the 520,000 eligible voters in the state.

The announcement released by the Secretary of State’s office points out that the high number of registered voters is the result of the voter registration system that launched in January 2017. This system permitted voters to register to vote automatically when they update their driver’s licenses or any form of identification at the Department of Motor Vehicles – a practice referred to nationwide as a motor voter law. Vermont’s motor voter law clearly succeeding in making it easier and faster for voters to registered.
