The paper is a brief essay on history of libertarianism in the USA with focus on libertarianism as a part of conservative movement. Authors emphasize the fact that many American writers and thinkers of the Right felt strong protolibertarian influence, so libertarianism had all the chances to become the leading current in new American conservatism. In the middle of the 20th century several writers from conservative m “National Review” magazine entertained the idea of “conservative fusionism”, but libertarians rejected it. More, such libertarian leaders as Ayn Rand and Murray Rothbard chose confrontation with conservatism. As a result libertarians distanced themselves from conservatism and in the end formed their own party becoming not just an intellectual but also a political movement. Still, Murray Rothbard after his “wilderness years” decided to join the Right again and even offered “paleolibertarian strategy”. But his attempt failed and strategy brought more bad than good to libertarianism, even discrediting the movement. The beginning of 1990s brought the alliance between paleolibertarians and paleoconservatives but no real political successes. Authors point out that in many ways libertarian strain damaged political career of Ron Paul. More, the legacy of paleolibertarian strategy may undermine presidential campaign of Senator Rand Paul – unless he rejects this legacy.
