The New York City Young Republican club split in two so long ago—all the way back in 1991—that the story of the schism is institutional legend. It had to do with state affiliation and interpersonal rivalries; the details (recounted by The Observer here) are sordid and ultimately trivial. They now maintain separate web sites—nyyrc.com, which is affiliated with the state G.O.P., and nyyrc.org—containing slightly differing accounts of the same history.
The .org group claims 500-600 members, the .com a thousand. Though accusations of fraud have been made by both sides, the current leaders have long since stopped rationalizing the clubs’ independent existence; it was just something that happened that no one got around to fixing.
