That really is Mark Block, chief of staff/CEO of Herman Cain's presidential campaign, talking up the candidate and smoking a cigarette. That really is Cain taking 10 seconds to smile at the end.
Feels like a parody of the now somewhat-popular "campaign manager gives briefing" ad, right? Only difference: This is amazing.
You know what else is real? This.
UPDATE: The video is boiled down to its essence.
UPDATE II: You want the full video for "I Am America," the song heard in the ad? Fine.
