I was going to make this a poll but screwed up.
I don't think Palin can be effective, because Obama will aim up on the ticket, not down at Palin no matter what she comes out with. Others will rebuke Palin, so I don't see this current offensive scheme having any success
Mccain has little energy left for this fight, IMO.
A 3rd party individual will have to be used(several). I would try to bait Obama into showing some real emotion, which he never shows, it seems. To do this, I would attack his wife, Michelle. She must have a long list of public quotes to dissect in her tenure. I would attack her in such a way that Obama would have to either defend her honor, or defend his race due to an implied slight. It won't be necessary for Obama to be truly offended(though that would help). Even if he is to feign anger, it might produce the hoped for result, seeing Obama as an angry, emotional black man. This might scare some people
That's the best I can come up with. I'd take the low road here
