I'm not sure how empty your life would have to be to think this is a good idea.
Leaders of the St. Louis Tea Party, including Bill Hennessy, Jim Hoft, Darin Morley, and Ben Evans, went to the arch grounds after the main Restore Sanity satellite rally was over to take pictures pretending that the crowd size was small. Here's a picture Hennessy took with the caption: "tens rally for democrats on steps of the arch:"
The St. Louis tea party official Twitter account also posted this picture with the caption"Restoring Sanity 10 people at a time"
Except that, unfortunately for the tea party, the Post-Dispatch was there during the actual rally, and they reported that 1,000 people were there:
(image credit: Post-Dispatch. BTW, this crowd is roughly half of what the tea party had when they hosted a rally for the entire middle third of the country)
For the life of me, I don't even understand why they would care about a comedy rally. Isn't it obvious that their best option would be to focus on Get Out the Vote efforts and simply ignore Stewart and Colbert? I think they look incredibly petty by getting so upset about a rally by a couple of Comedy Central comedians (however great those comedians are) asking for sanity in political discourse.
