ReTeaParty.com was involved in the past tea parties in some way and is currently planning a series of "parties" for July 4. At their site, they stress how independent and non-partisan they are. "Non-partisan" in this case apparently means "anyone who isn't reflexively sickened by Randroids", as they offer a video entitled "This is John Galt Speaking | A Montage of Modern History": link.
