When Hillary's 3am phone call ad came out, I -- and others -- suggested it made more sense as an ad for John McCain. Turns out that was truer than we knew. Here's an ad some McCain support uploaded to YouTube 3 months ago. Same premise, far more effective.
The primary legacy of Clinton's ad may be making it harder for McCain to re-release this one a couple months from now, as the media will mock him for biting Clinton's failed scripts. (Kudos to Buzzflash for the find.)
