A Nov. 9, 2006 enforcement decision by the Federal Election Commission (FEC) expands federal campaign finance regulation to voter guides that do not endorse or oppose candidates if the FEC determines the guide's overall content implies support or opposition to federal candidates. The case arose from a complaint filed in December 2004 by Edmund A. Hamburger of Pinellas Park, FL, which claimed "the Sierra Club was advocating the election of Senator Kerry to the Presidency of the United States." On Nov. 9, the Sierra Club chose to settle the case and pay a $28,000 civil fine rather than incur further legal expenses, but denied any wrongdoing. The case could discourage future efforts by advocacy organizations to educate voters about candidates' track records.
