I like how Nate Silver's new scale for the dishonesty of polling analysis is done on a scale of one to five Penns. I remember Mark Penn's work well -- if you just looked at the underlying polls, it would often be obvious that he was trying to scam you.
In addition to being dishonest, Penn was incompetent at everything except preventing Democrats from doing useful stuff. (Why Democrats tolerated a strategist who ran a firm that gave more money to Republicans than Democrats is beyond me.) Keeping him away from the White House was a solid reason to be an Obama guy rather than a Clinton guy. I hope Penn's days as a major force in Democratic politics are over, and I'm glad Nate's helping to bury him.
