So how does this process work today? Do you have to actively register beforehand if you plan on voting? Why though 😅

further elaboration: the US Fed passed a law that required very close to the thing this state is doing, called National Voter Registration Act of 1993 or "Motor/Voter Act", since the kinds of documentations most citizens need for driving licenses is the same as needed for voting registration.

In the US, each citizen has to register to vote. States have their own rules, some of which are fairly restrictive. Non-profits and political groups run "voter registration drives" and go door-to-door or text campaigns to reach unregistered people, but it's difficult and costly.
