Well-placed politicos say there’s a stealth campaign by outside groups to influence the mid-term elections, but my colleagues Ryan Sibley and Aaron Bycoffe from Sunlight’s Reporting Group have dug into the electronic paper trail left by these organizations and made a tool tracking all the 2010 independent expenditures so you can too.

Some $57 million has been spent so far in 2010 by organizations ranging from the 60 Plus Association, a nonprofit that doesn’t have to disclose its donors, to party committees like the Democratic Senatorial Campaign Committee to labor unions like the Service Employees International Union and the American Federation of State, County and Municipal Employees which are taking advantage of the Citizens United ruling to directly influence elections.

Find out who’s spending where on which candidate, and read our take on what it all means.
