The Federal Election Commission has threatened Christine O’Donnell with an audit or other “enforcement action” regarding what appear to be incomplete campaign filings from her unsuccessful Senate bid.

It’s a relatively common warning for federal candidates but could attract widespread attention because of the tea party favorite’s star power in the 2010 election cycle. The Delaware Republican has until Dec. 21 to provide updated figures for a handful of donors listed on her first-quarter 2010 report, according to a Nov. 16 letter from the FEC to her campaign. “An adequate response must be received at the Senate Public Records Office by the response date noted above. Failure to adequately respond by the response date noted above could result in an audit or enforcement action,” reads the letter from Vicki Sue Davis, a senior campaign finance analyst with the FEC.

O’Donnell is hardly the only candidate this cycle to receive such a warning from the FEC. While the agency could not immediately provide the total number issued this cycle, dozens of candidates for federal office are typically forced to amend their filings under the threat of an audit.

O’Donnell made international headlines after defeating Rep. Mike Castle in the First State’s GOP Senate primary. Seizing on her newfound fame, she raised more than $5 million to fuel a campaign that ultimately suffered a nearly 17-point defeat at the hands of Democrat Chris Coons.

Her history of financial mismanagement — in addition to questions about her education and brief exposure to witchcraft — drew repeated fire from Democrats and Republicans alike throughout the campaign.
