Although she rejected the labels "conservative" and "libertarian", Rand has had continuing influence on right-wing politics and libertarianism. Jim Powell, a senior fellow at the Cato Institute, considers Rand one of the three most important women (along with Rose Wilder Lane and Isabel Paterson) of modern American libertarianism, and David Nolan, one of the founders of the Libertarian Party, stated that "without Ayn Rand, the libertarian movement would not exist". In his history of the libertarian movement, journalist Brian Doherty described her as "the most influential libertarian of the twentieth century to the public at large" and biographer Jennifer Burns referred to her as "the ultimate gateway drug to life on the right". Economist and Ayn Rand student George Reisman wrote: "Ayn Rand...in particular, must be cited as providing a philosophical foundation for the case of capitalism, and as being responsible probably more than anyone else for the current spread of pro-capitalist ideas."
