I just set my TiVo to record the Stewart/Colbert rally on Saturday, October 30 on Comedy Central — from 9 AM until Noon on this coast, though I padded my recording by a half an hour, just in case. At the moment, it looks like that's the one time the network is running it that weekend. Listings on my TiVo only extend as far as midday the following Monday so maybe it'll rerun after that…but maybe not. I'm curious if C-Span will be covering it and if so, if their coverage will differ markedly. We shall see.
This article by Timothy Noah, a writer I usually like, thinks they ought to cancel the rally because seeing all those "elitists" out acting hip on the National Mall will just piss off the Tea Party crowd and those that lean in that direction and mobilize them to vote. I think that crowd is already fired-up enough to do that and maybe Stewart and Colbert can fire up the voters who, however direction they lean, aren't out there chewing on their furniture. Then again, maybe all they'll do is just put on a good show. That's reason enough to do it.
