Within 60 days of an election, every dollar spent by a candidate has the same television advertising buying power as $1.63 from any non-candidate source, according to a new analysis of advertisement contracts in the Las Vegas media market. During this period, FCC regulations mandate that TV stations charge candidates “no more per unit than the station charges its most favorite commercial advertisers” for the same ad time. As it turns out, this preferred status nets candidates a significant discount over super PACs, dark money organizations and party committees. According to this new data—collected through Sunlight’s Political Ad Sleuth—candidates enjoy an average markdown of $364 off their typical $946 price tag for a thirty second spot, which constitutes a 38.5 percent price cut. This helps to explain why, as Ezra Klein has pointed out, ads from Obama and his allies have been more frequent than ads from Romney and his allies. Because more money on the Republican side has been flowing into the election through super PACs and other outside groups, the GOP’s purchasing power is diminished.
