Just to be clear, I thought Saturday's rally was a significant event and the crowd size was impressive. But as I've been saying since the event was initially announced, the "both sides" meme tainted and diminished what it could have been: an adrenaline boost for a disillusioned left, along with a primer about how to get tough without going crazy.
They did an unfortunately clumsy bit at the end which indicated both sides were equally bad and Jon gave a very uninspiring speech about how both sides need to calm down. (Of course the only ones who will hear it are liberals, but whatever ...)
Like Digby says, right wing isn't going to listen to any of this. So basically DFH's just got told to STFU.
Of course that wasn't Stewart's intention, but it's the unfortunate consequence of the "both sides" meme that appears to have infected, well, almost everyone.
