How do you ensure voter lists are accurate?

We take voter list accuracy very seriously because having robust and accurate voter lists is the first step in ensuring the integrity of our elections. Our priorities are to ensure every eligible voter and no ineligible voters are on our voter list.

We regularly receive updates from other state and federal agencies regarding address changes, deaths, felony incarcerations, and other life events that may impact voter registrations. We are constantly updating the state voter database to reflect these changes so it's as current and accurate as possible.

You can withdraw your voter registration, or notify us of other changes at any time.
