The Libertarian Party of New York (NYLP) has an active Facebook group, but for a long time no Facebook page. On May 29th, an official one was created. It’s available below:
Currently, there is only one LP state affiliate without a Facebook page (Oregon). However, there are several state pages that are rarely active, with some not having any new posts since the fall of 2012, for example. One, the South Dakota Libertarian Party page, has not had any posts since its creation.
