What sort of conservatism blends Jesus with Ayn Rand? Oh, that would be contemporary Tea Party conservatism.
But why isn’t it more widely noticed that “Christian libertarian” is an oxymoron? I would argue that this has to do with the human mind’s capacity for compartmentalization and cognitive dissonance, for Jesus and Rand simply do not go together coherently. Buckley, before he died, was less illusioned: he saw that his Catholicism and Randianism are not a match. Rand herself recognized this as well. She was an atheist.
Prometheus Unbound 
There’s a much more “Christian compatible” moral justification for libertarianism out there, so it seems unneeded as well. But is it really any revelation that most people don’t think their belief systems all the way through? As an aside, I might I recommend a particular episode of a libertarian podcast? I think you might find it interesting:

I can’t add much, other than it has always amazed me that Christian conservative like Ayn Rand, when she was such a militant atheist.
