“The practical impact of the decision is small. Groups seeking to elect or defeat candidates have largely abandoned so-called electioneering communications ads in favor of telling voters how to cast their votes. Donor disclosure for such independent expenditure ads is only required when the contributors donate ‘for the purpose of furthering the reported independent expenditure.’“The decision is a blow against groups seeking to influence the public debate on issues. The disclosure rules will force such speech off the airwaves.“The Independence Institute v. FEC case warned of that result. That litigation provides the courts with an opportunity to protect genuine issue speech from the chill of badly tailored disclosure laws.”
