Campaign advertisements; independent expenditures; electioneering communications; disclaimer requirements. Broadens the scope of disclaimer requirements for campaign advertisements to include electioneering communications, as defined in the bill, and messages advocating for the passage or defeat of a referendum. The bill also requires an advertisement that is an independent expenditure or that expressly advocates for the passage or defeat of a referendum to contain a disclaimer providing the names of the advertisement sponsor's three largest contributors. The bill also requires independent expenditure reports to be filed electronically. Current law allows such reports to be filed either electronically or in writing.
