Even when a Democrat uses it.
Even against Rand Paul.
I bet it doesn’t work: Christianity, like patriotism, is a weapon that probably can’t be pointed to the right. Yes, in principle the born-agains should hate the Randites, since Ayn Rand was just muddled Nietzsche. But I don’t think it works that way. To the Tea Party types, “Christian” just means “one of us.” So Obama isn’t a “Christian,” and Rand Paul is.
Footnote: The “Aqua Buddha” story has two aspects: the blasphemy or worse (from a Christian perspective) and the maltreatment of the woman. Of the two, the less culpable aspect is the more politically charged. Conway doesn’t seem to be concerned about Paul’s having tied a woman up; he’s complaining about “asking her to worship a false idol.” (Not to be confused, seemingly, with all the true idols it’s perfectly OK to worship.)
Alas, violence against women doesn’t make someone “not one of us” to the median Kentucky voter.
