It would appear that the remaining 265 members of the Pasadena Ron Paul Meetup group have no interest in a MoveOn.org anti-war rally. Given that eight RP Meetup members responded and we will assume for purposes of discussion that they all actually wished to attend and protest the war, that would mean that just barely 3% of the Pasadena Ron Paul Meetup group has any interest in anti-war protests or MoveOn rallies.
First, we have the original post page. It consists of only three posts, all by the event organizer, Karsten.
Second, we have Karsten himself. A college junior, flips between Dim, indie, Libertarian, Republican, etc. He's managed to register as a lot of things for a guy who's only voted in one presidential election. Notice his own signup date of August 18th. Karsten himself has only been a member of the Ron Paul Meetup there for less than ten days (but is inviting people to "invade" a MoveOn anti-war event). Karsten would seem to be as much an "invader" of the Ron Paul Meetup as any of the Pasadena group are "invaders" of a MoveOn event.
Third, we have the responses to Karsten's invitation. One RSVP besides Karsten himself (the guy with the anti-war jerky). Four said "maybe" (only three are RP Meetup members. And three RSVP'd as "No".
It'll probably be Karsten with one guy from the RP Meetup and a dozen MoveOn anti-war types. Of course, the MoveOns will likely fail to show up too. In the end, Karsten will be lucky to get 8-10 people standing on the street holding signs.
