Some intellectuals who have helped shape the modern neo-Confederate movement have been associated with libertarian organizations such as the Mises Institute. These individuals often insist on the South's right to secede and typically hold views in stark contrast to mainstream academia in regards to the causes and consequences of the American Civil War. Zack Beauchamp of "ThinkProgress" argues that because of its small size, the libertarian movement has become partially beholden to a neo-Confederate demographic. In contemporary politics, some libertarians have tried to distance themselves from neo-Confederate ideology while also critiquing President Lincoln's wartime policies, such as the suspension of "habeas corpus", from a libertarian perspective.
