Here's an ad hitting McCain on his "maverick" image. It's pretty good:

"Now Obama is starting to play by Karl Rove rules. Hit your opponent at their strength. McCain's strength has been his long-since-vanished reputation as a maverick. And it's about time. A lot of Dems are upset that Obama has let the attacks gone unanswered for so long:

On McCain, the Obama people are missing a golden opportunity with this tire pressure thing. Hit McCain back in the teeth. "Of course he wouldn't understand, Millionaire McCain hasn't driven in years. He's been in a chaffeur-driven limo, or on his wife's plane. Jet-setting among his 10 house. He wouldn't know a tire gauge from a Web page.

"Hit the man in the teeth. piss him off. Start calling him Daddy Warbucks. Seriously, pull out the stops. It puts all of the critiques together. He's old. He's a war monger. And he's rich. Why the hell didn't they put out an ad saying McCain was gonna make million off the sale of Budweiser? Jesus, this is getting ridiculous. Hit McCain in his wheelhouse and piss him off. All it will take is McCain losing his cool once and he'll drop like a stone. The ads write themselves."
