I've noticed that as well... very disappointing.
If it makes you feel any better, Talent ran a new ad during the World Series tonight, here in St. Louis, directly taking on the Michael J Fox ad. As far as I recall it ran once. All the other ads I saw from the Talent campaign and the RNC in support of Talent all attacked McCaskill for being a lying bitch and marrying one of the people she was supposed to audit. Many more ads tonight then I have seen from Talent. He seems to finally be outspending McCaskill.
Was it an ad with Talent himself speaking about the M. J. Fox ad or was it the one with Jeff Suppan, Mike Sweeney, et al? Anyway, that's good news... I hope he continues to outspend McCaskill, and wins this election.
