Voters’ mailboxes are brimming with campaign mailers as the Aug. 2 primary approaches. But the source of the funding for groups sending out these mailers is not always clear. AZPM's Andrew Oxford examined the fine print on some mailers and found one donor funneling millions into a U.S. Senate race and outside groups spending nearly $100,000 to influence a Democratic primary for state Senate in Tucson.
