"I consider myself primarily to be a libertarian," says P.J. O'Rourke, the author of the new book How the Hell Did This Happen?: The Election of 2016. "I am personally conservative [but] I always think of libertarianism as basically being an analytical tool, not an ideology per se.... When you look at something that happens, especially in politics, you look at something that happens, you say, 'Does this increase the dignity of the individual? Does this increase the liberty of the individual? Does this increase the responsibility of the individual?' If it meets those three criteria, then it's probably an acceptable libertarian political policy, or lack thereof, because we like to subtract some things from politics too."
