The Libertarian Party is in turmoil again — this time over an anti-war rally and march planned for Washington, D.C., on February 19. The vice chairman of the party has resigned, prominent Libertarian figures are speaking out, and Twitter is aflame.

At issue is the roster of speakers for the event, the Rage Against the War Machine rally, which is being organized jointly by the Libertarian Party and a left wing populist party run by a former Bernie Sanders campaign staffer, the People’s Party. The speakers include big names such as a former congressman and Republican presidential candidate, Ron Paul; a former congresswoman and Democratic presidential candidate, Tulsi Gabbard; and another former congressman, Dennis Kucinich. A comedian and political commentator, Jimmy Dore, and a judicial analyst, Judge Andrew Napolitano, are also set to speak.
