I'm quite old :). Old enough to have been involved in quite a bit of conservative politics over the decades. I'm certainly old enough to have studied it and know its history.
You seem to have forgotten Russell Kirk's "The Conservative Mind" published in 1953 and William Buckley's founding of National Review in 1955 at which time, in his mission statement he described it as "a conservative weekly journal of opinion.. It is out of place because, in its maturity, literate America rejected conservatism.."
Just how old were YOU in 1953?
