I reckon not, a couple of sentences taken out of context from a single interview when during the rest of the interview he proceeded to politely distance himself from them, from 35 years ago is not much to build a myth on, even the New York Times wouldn't try that hard to build a sand castle.
American conservatism and libertarianism are very similar if not nearly identical in most ways.
I would say that the key difference is Americans Conservative general respect the right of the state to institute some level of social polices.
Conservative also tend to be more aggressive in foreign policy.
But as far as the Federal movement’s domestic policy goes we are mostly in agreement, the same with the State government domestic policy’s in most western states.
Conservatism is largely not to have an ideology, but rather the desire to preserve and restore the best parts of our roots.
It is because of the nature of our roots in the United States that American Conservatives are a natural ally of libertarians which is an actual ideology.
All of this is due to the fact that America has Libertarian roots, Our founders with few exceptions such as Hamilton(imperialist) were mostly Libertarians.
This is particularly true of Thomas Jefferson.
Anyway as a result American conservationism is largely by definition Libertarianism.
This is not true of “conservative” most anywhere else in the world, thou we have been rubbing off on them by association. (Sadly so have they, but not as much because their roots in imperialism don’t sell like ours in liberty.)
