The Supreme Court has in recent years famously struck down laws that barred corporate electioneering on First Amendment grounds. But the Court has had little problem with laws that demand disclosure about who is contributing to elections and how much (though the Court protects anonymous speech in other contexts). With that in mind, read this L.A. Times article describing proposed new rules in New York that would require non-profit groups that do electioneering to dislose their budgets and their donors. Here's an excerpt:
The push by states to force politically active nonprofits to disclose
their financial backers ratcheted up Wednesday as New York's attorney
general proposed tough rules that could require many such tax-exempt
groups to publicly report their political budgets and donors. The regulations, which Atty. Gen. Eric T. Schneiderman plans to issue in
spring after a public comment period, could affect some of the biggest
outside groups that engage in federal political campaigns, including American for Prosperity, the League of Conservation Voters, the National Rifle Assn. and NARAL Pro-Choice America.
