We've done a bit of reporting on the efforts of Arizonans for a Brighter Future to knock out the incumbents on the Pima County Board of Supervisors here and here. To recap: ABF is a non-profit business league funded with dark money and headed up by developer Mike Farley, who is unhappy with the current Board of Supervisors and Pima County Administrator Chuck Huckelberry.

ABF is now funding Restoring Pride in Pima County, a political committee that is presenting a series of web videos called "The Pima Bunch." The debut episode, which you can watch above, promises to reveal a web of cronyism behind the power structure in Pima County.

We'll see how persuasive this particular effort turns out to be. The key race is District 3, where Republican Tanner Bell wants to defeat Pima County Supervisor Sharon Bronson. Bell's most recent campaign-finance report showed that he didn't have much money to get his message out, but new reports are due this week. In the meantime, Arizonans for a Brighter Future is hoping to do at least some of Bell's work for him by attempting to drive up Bronson's negatives.
