Federal Court Reinstates Online Voter Registration

Pursuant to a federal court order issued last night, the Wisconsin Elections Commission (WEC) is working to reactivate the online voter registration functionality of MyVote Wisconsin through March 30, 2020.  

WEC staff is attempting to implement the Court’s decision as promptly as possible. This will require developing changes to MyVote Wisconsin, testing and then implementing those modifications.  Especially this close to an election, it is important that they ensure that these changes are implemented successfully and that they do not inadvertently impact other functionalities of the system.

It is equally important that all local election officials are aware of the Court’s order and comply with it consistently throughout the State; the city of Sun Prairie is dedicated to this goal. WEC staff hopes to complete the change back to online registration within a few days (please be patient with them and us) and will inform clerks and the public when that functionality is again available. The city of Sun Prairie will work just as diligently to ensure our residents are provided with the most current information.
