The cloak of secrecy over "social welfare" tax-exempt organizations which have been lawfully engaging in political activity, while shielding the identity of their contributors, will end, at least temporarily. Now, all federal political activity will require donor disclosure.
The FEC advisory does not specifically mention 501(c)(4) organizations, which were the primary means for circumventing the FEC's total disclosure policy. However, it should be clear that 501(c)(4) organizations are the target.
