There's been a lot of talk this week about the Herman Cain ad in which his chief of staff, Mark Block, is seen smoking. But it's really just the latest "What was he thinking?" moment in a string of mixed messages and indecisive tactics from the candidate. Below, check out the little video where he sings "God Bless America" over footage of the World Trade Center burning down and a background track of screams, then looks dejectedly off camera as an animated logo plugs his presidential campaign. Or the one that starts out as a fictional trailer for a Wild West film called He Carried Yellow Flowers (with a cock joke and a liberal black man getting punched), and then becomes a weird campaign testimonial. Or rock along with the Herman Cain Train Country Music Video. Somebody needs to grab this ad campaign by the reins and steer the burning stage coach away from that big ole pile of TNT before it blows up in Cain's face. We've pointed out before that Cain has genuine marketing credentials and two decades' worth of brand-building savvy. And he's got the catch phrases down. So, what gives? If history has taught us anything, it's that Cain needs to find a graffiti artist to make his ads shine. And hey, there's one with good directorial cred now too. Hop that train, Cain, before it leaves you standing alone on the platform.
