This Mike Huckabee ad is all over the place.
Sully links to RedState saying it is "insanely good," as well as Ezra Klein, who (despite some criticism) calls it "The Greatest Ad Ever." Mathew Continetti at "Campaign Standard" thinks it "is funny and fresh, but in terms of substance it's lighter than air." Yglesias calls it "strange but funny."
Well, funny it certainly is. I have to say, though, that I agree with Ezra Klein: the ad is funny if you know about the whole phenomenon of "Chuck Norris facts." As a viral video it is incredibly good -- everybody's linking to it and embedding it, after all. But won't the average voter be a bit confused by Huckabee's claim that Chuck Norris moves the Earth when he does pushups?
