Relating to: coordination of mass communications.

This bill updates Wisconsin's campaign finance laws by creating new definitions for mass communications, including mass distribution, mass electronic communication, and mass telephoning, each requiring at least 500 pieces of substantially identical material or messages. It modifies how coordinated expenditures are defined for express advocacy and mass communications, specifying that coordination occurs when a candidate or their party exercises control over or engages in substantial discussions regarding the content, timing, or other aspects of a communication. The legislation also establishes reporting requirements for coordinated mass communications made during the 60-day period before an election, requiring political committees to report expenditures and candidate committees to report them as contributions. These changes directly affect political action committees, independent expenditure committees, and candidates by clarifying what constitutes coordinated spending and how such spending must be reported under existing contribution limits and source restrictions.
