A new TV ad boosting Republican Sen. John McCain is hitting the airwaves in Arizona, though it's not entirely clear who's behind it. The spot features footage of the aftermaths of both the Paris and San Bernardino terror attacks as a lead-in to contrasting clips of President Obama ("We have contained them") and McCain ("We're gonna have to kill them") talking about ISIS.
According to Roll Call, the ad is backed by a $90,000 buy and will appear mostly on Fox News, suggesting that it's aimed at shoring McCain up with primary voters. But who's paying for it? Roll Call says it's from a group called A Secure Arizona (whose website is about as unrevealing as they come), and the video itself is posted to a YouTube account with the same name. However, in the ad's final frame, a written disclaimer says the spot was "paid for by Citizens for a Working America." Their website is an even bigger joke, and a diligent Sunlight Foundation investigation into their backers several years ago turned up little.
Either way, this is a classic dark money expenditure that's designed to be as opaque as possible.
