Wisconsin voters will decide if there should be a state constitution requirement to produce valid photo identification for future elections.

A proposed state constitutional amendment requiring a photo ID to vote in Wisconsin elections is expected to receive final legislative approval as early as Tuesday.

The Wisconsin State Assembly passed a proposal Tuesday that could enshrine voter ID requirements in the state constitution if the majority of Wisconsin voters support it. The passage sets it up to go to Wisconsin voters in April — on the same ballot as a consequential election for the state Supreme Court.
