Two weeks ago, I flagged a report by our partner organization Political Correction documenting how the GOP slush funds promoted by Fox News political analyst Karl Rove had aired 17,360 ads between August 1 and October 11. Rove's little elves have been busy since then -- American Crossroads and Crossroads GPS have funded more than 10,000 additional ads between October 11 and October 24, according to a new Political Correction report.

Notably, 15,210 ads since August 1 have been aired by Crossroads GPS, a 501(c)(4) organization that does not disclose its donors.

As Politico's Ken Vogel reports this morning, Crossroads GPS was “spun off” of the original 527 organization because potential donors were “leery of having their names disclosed.” Meanwhile, Rove and the right-wing media continue to use misleading spin and false equivalences to defend those anonymous donations.
