We missed it between Christmas and New Years, but Heartland Revolution registered as an independent expenditure only committee with the Federal Election Commission. Such committees, also known as Super PACs, can take contributions in any amount from any source, and spend that money influencing federal elections.

Heartland Revolution shares a Post Office box with John Waltz for Congress, the eponymous campaign committee for the Democratic challenger to Rep. Geoffrey Davis, R-Ky. In filings with the FEC, the committee discloses just one official--Janie Waltz, which is the name of Waltz's wife.

Super PACs are bared from coordinating with federal candidates.
