Data source: Wisconsin State Legislature website

Our database includes records of how each member of the Wisconsin State Legislature voted on every bill.

The official record of this information is published on the Wisconsin State Legislature website. The bill information is updated nightly after the Legislature has completed its work for the day.

With the help of the Sunlight Foundation's Open States Project, we pull in updated information in the early morning on a daily basis. On a given day, MapLight will be displaying all bill actions (such as introduction, passage, enrollment or veto) up through the previous day.
