Just got word of what sounds like one of the first Second Life rallies in support of a presidential candidate. According to a group notice I got from the Capitol Hill group, supporters of Barack Obama will gather on Saturday March 31 at 2:30pm PST at SL Capitol Hill (teleport SLURL) for a rally to show some love for the democratic senator from Illinois.
UPDATE, 3/30/07: I've heard back from some of the principal organizers. The in-world group "Obama for President" led by avatar Cubsfan Pugilist (gotta love that name) is leading the rally at 2:30PM on Capitol Hill. The in-world marketing firm Forefront Media is organizing the in-world video stream of the Obama webcast on Soho island (teleport SLURL) at 1PM. They are not formally associated with each other in any way.
