UPDATE 2: Oh the irony! CNN has a quick poll asking “Is the Jon Stewart, Stephen Colbert rally on Washington D.C. serious or just a stunt?” Proof that CNN just doesn’t get it? I don’t know how long the poll will be up, but if you scroll to the bottom of this page, you can let them know what you think. Right now, it is running over 2 to 1 for “serious”.
