How so? Catholic traditionalism dates back to Pope Pius X's 1907 encyclical Pascendi Dominici Gregis. Political conservatism is secular.
Catholic traditionalism dates back as long as you want to trace it back, even, like Carrie does, to times before the Incarnation; I only chose the Crusades because that is a relevant point in modern politics. But “Catholic” and “modern” should never be in the same sentence, and I spoke of modern conservatism. The latter is heavily laced with laissez-faire, which makes it a defensive phenomenon.
It really starts with the Emperor Joseph of Austria in the 1780s. You know, the Enlightened One.
