Obnoxious, and not just because he’s ruining a Beatles song (again). Those campaign ads of his that got so much attention were cheeky and harmless as a bleat for attention from a guy who’s otherwise off the national radar screen. His subject here is deadly serious, though, and yet it’s played as camp — grandpa mugging along to Charles Manson’s favorite song intercut with images of the Trade Center collapsing, then capped with a cutesy-poo “Number nine, number nine.” The military-industrial complex is a dire threat indeed. Would Mike Gravel be making electronic remixes if it wasn’t?
