Surely Goldwater was New Right? At least in a proto sense?
I certainly think so. The Old Right tended to be anti Jew and isolationist. Goldwater was neither. But to the extent that the New Right is tagged with social conservatism, that was not Goldwater's bag at all. There is so much mischief attending semantics isn't there?
I don't think the American Old Right tended to be anti-Jew, though there was an element that was.
Goldwater's campaign in 64 involved the rise of the New Right with Buckley and others. He was a transition between the Old and New Right, but with his hawkish emphasis I'd place him in the latter camp.
