This is a 30-second ad - signed, sealed, delivered. No voiceover just 25 seconds covering the main comments (pig, fish, laughter) and then fade in "Change we can believe in?" Done.
Indeed - done right, this can be the famous "mushroom cloud" ad for McCain and Palin. 10 seconds of Palin addressing a huge, cheering crowd, including her "lipstick on a hockey mom" comment. Fade to Obambi making his "lipstick on a pig" comment. Then fade to "Change we can believe in?"
The "fish" comment can be used later in another ad.
Obambi is eliminating himself, but it's up to the McCain campaign to provide the assist. The drive-by media won't help at all.
