Over at the Campaign Spot Jim Geraghty asks whether John McCain is too nice a guy to use Hillary’s ad against Obama with one modification: After the voice-over that says “I’m Hillary Clinton and I approved this ad,” he wants to add “And I’m John McCain, and I approved the ad too.” Brilliant — if Obama is the candidate. But one of my readers had a great idea if Hillary is the candidate. Actually, she thinks a tougher Obama would use it now…. Same ad, but towards the end, when the phone is ringing, a momentary shot of both Bill and Hillary reaching to grab the phone. There are a lot of things the voice-over could say….but I would start with “when that phone rings…. don’t you want the person you elected to answer it.”
