Primary elections

Wisconsin has open primaries: there is no party registration, and on primary day you choose one party’s ballot. You can vote in only one party’s primary.

Voter ID

Wisconsin requires a photo ID to vote in person. If you don’t have acceptable ID, you can vote a provisional ballot, but you must take extra steps after Election Day (such as showing ID at the election office) for it to count.

Early voting

Starts: Fourteen days preceding the election (in-person absentee). Ends: Sunday preceding the election. Locations and hours are set locally.

Voting by mail

Any Wisconsin voter can request an absentee/mail ballot. No excuse is needed.

Your local election office

In Wisconsin, many elections are run by your city or town clerk rather than the county. Find contact information for your local election office on Wisconsin’s official election website.
