Politico offers this important report. This is an unsurprising consequence of the new campaign finance regime. I wrote in a Slate column a few weeks back, “as I predicted, funding to the Rove political group American Crossroads skyrocketed when he opened up a 501(c)(4) affiliate, Crossroads GPS, to take anonymous donations. The Chamber, meanwhile, is a 501(c)(6) trade association, and it, too, does not have to disclose its members or their contributions publicly.” That earlier prediction came in April, in a column entitled “Hushed Money: Could Karl Rove’s new 527 avoid campaign-finance disclosure requirements?”
