Georgia quietly ends automatic voter registration for 15 months
Since 2016, Georgians who received a driver's license have been registered to vote by default. Georgians that didn't want to register to vote had the opportunity to opt-out. But, early in 2021, a change was made to the system. Instead of automatic registration, applicants were required to affirmatively click a "YES" button in order to register. That change caused a dramatic decline in new registrations.
