Registering to vote is easy and painless in Wisconsin. A qualified elector (one who has resided in the district in which he or she intends to vote for at least ten days) can register in advance by calling your local municipal clerk’s office, but you can also register the day of the election in just minutes.
To do so, bring a valid Wisconsin driver’s license with your current address. If you don’t have that, you can bring your Wisconsin Driver’s license or Wisconsin ID card, as well as a piece of substantive mail, such as a cable or utility bill (not junk mail) addressed to your current physical address (no PO Boxes). You will be asked to fill out a short form, then you’re set to vote.
