A report from the Sunlight Foundation:

Less than three hours after Democrat Tom Barrett conceded the $63 million-and-counting contest to Gov. Scott Walker, Americans for Prosperity, the big spending conservative group, sent an email to supporters hailing Walker’s win and including a video highlight reel about “how AFP educated Wisconsin residents about Governor Walker’s budget reforms.”

So how much has AFP reported spending on the Wisconsin campaign?  According to Wisconsin’s Government Accountability Board, the agency that tracks campaign expenditures in the state, nada. “AFP has not registered with us,” reports Reid Magney, a spokesman for the GAB. 

Nor is it likely to do so. Americans for Prosperity, which reported revenues of $22 million in 2010, claims immunity from such paperwork because, it is a non-profit organization…

In case there was any doubt:

 ”Together, we’ve helped restore prosperity to the Badger State,” the AFP email closed. “Now, onto the rest of America.” In case that was too subtle, the embedded video ended with three words on the screen: November Is Coming.”
