On the subject of "issue" ads, I heard that Pepsi/Apple are going to air an ad featuring kids sued by the RIAA "thanking" pepsi and apple for allowing them to download music legally using iTunes. While it isn't as politically charged as flaming the president, the fact that CBS allows this kind of ad and not the moveon ad seems a little bit hypocritical.
Maybe moveon needs to get a cosponsor! Perhaps all those kids could be munching on Doritos while they work.
