Milling around the Jon Stewart/Stephen Colbert rally today, I couldn't quite figure out the point. The acoustics were so bad also that you could barely hear anything unless you were right by the stage. Straining here and there, I was able to catch a smattering of dialogue but Colbert and Stewart really could not be heard during most of the time in the various locations I was at. Not being able to hear anything didn't seem to bother most of the attendees however, most of whom were wandering around looking at many of the funny (and attempted funny) signs.
Not all of the signs were trying to be funny, however. Most of the ire of the angry demonstrators seemed to be directed against Glenn Beck and Fox News. There were also a few anti-Republican signs as well, including at least one of Republican politicians Sarah Palin, John Boehner, and Eric Cantor with Adolph Hitler mustaches alongside conservative talk show hosts Glenn Beck and Rush Limbaugh.
I took several shots of the rally, see them below or view them fullscreen here.
