• IA-04: Democrat Jim Mowrer is one of the few challengers to hold more cash on hand than the person he's trying to unseat. Mowrer, who is taking on unhinged Republican Rep. Steve King, is taking advantage of his financial edge to air his third spot of the cycle. Mowrer describes how he lost his father at a young age, and the family only survived because of Social Security. Mowrer then declares he'll defend Social Security.
While Mowrer has the privilege of running against one of the nuttiest members of Congress, his spots have been all positive so far. Mowrer has heavily played up his local roots and his military service in his first and second spots. So far, King and his allies have not been on the air at all. Romney won this seat 53-45, and King turned back a well-funded challenge last cycle by a similar margin. King may feel he has nothing to worry about: We'll see if Mowrer's spots make him feel any differently.
• GA-Sen: We recently highlighted an EMILY's List buy for $1 million, and now we have the ad. The narrator accuses Republican David Perdue's company of discriminating against women while he ran it. Meanwhile, the NRSC shells out another $478,000 against Democrat Michelle Nunn (here and here).
• AZ-Gov: With the Aug. 26 Republican primary almost here, former Mesa Mayor Scott Smith has two last minute positive ads (here and here). We also have a very rare sighting: An ad for Secretary of State Ken Bennett. Bennett has long been an afterthought in this contest, with his opponents and their allies not even bothering to attack him. Bennett's own ad is pretty dull, with him just talking to the camera.
• FL-Gov: Next Gen Climate ties Republican Gov. Rick Scott to big polluters. In what's become a big theme in anti-Scott ads, the spot throws in a clip of Scott evading questions at a hearing over his then-company's alleged Medicare fraud.
• IL-17: Democratic Rep. Cheri Bustos' first spot features a veteran decrying how too many American flags at military funerals were actually made in China. The man praises Bustos for introducing a bill to require the government to only buy American-made flags.
Weirdly, the narrator declares, "The [Belgard] ad falsely states MacArthur cheated disaster victims." As a viewer (albeit one not inclined to like Tom MacArtur to begin with), the only part of the ad is the "MacArthur cheated disaster victims" line.
