Eric at TPM has a great idea:
And here's the ad: A one-minute spot featuring Hillary Clinton herself, talking to the camera and laying into Palin on the issues, her complete lack of qualifications, and the temerity of the McCain campaign to think they could get away with this. Then she urges anyone watching who might have supported her to get out there and support Barack Obama.
Then it closes simply with Obama walking on to the set to shake Hillary's hand: "I'm Barack Obama, and I approved this message."
They better do this one. It would be legendary.
