Stewart rally gathering steam

Here's a bit of data bearing out the anecdotal suggestions that Jon Stewart's "Rally for Sanity" is getting the broader traction that "One Nation" didn't.

There are, at present, 228 groups in more than 200 cities on the event-organizing site MeetUp.com organizing their own local mirrors of the event. The Tea Party movement, as Glenn Beck has celebrated, grew in part through MeetUp events around the country.

This is still small potatoes, relatively to the energy on the right: A person who works with MeetUp tells me there have been 2,507 Glenn Beck Meetups drawing nearly 15,000 RSVPs in the last 30 days. But it's probably a page worth watching over the next month.
