I was there today. It wasn't so much anti-CNN (although that "reporter" was the arrogant and clueless one I've seen in awhile), as it was anti-big spending, anti-tax, and anti-incumbent. Maybe she thought it was orchestrated by Fox because Mancow was there.
I was there, part of the time (noon-12:25). I was surprised that so many people attended. Part of the time, I could barely move.
