In Wisconsin, the legislative process starts when a senator, constituent, group, or agency proposes an idea for a bill. After drafting, the bill is introduced, numbered, and referred to a committee for review and public input. If approved, it moves through three readings and votes in both the Senate and Assembly. Once both chambers pass the same version, the bill goes to the governor, who can sign it, veto it, or let it become law without a signature. Only a small share of bills introduced each session ultimately become law. You can learn more about the Wisconsin legislative process here.
