Conservatism is, among many other things, a culture. The most important glue binding it together is a shared sense of cultural grievance - the conviction, uniting conservatives high and low, theocratic and plutocratic, neocon and paleocon, that someone, somewhere is looking down their noses at them with a condescending sneer.
I like to imagine, as a thought experiment, the day, perhaps not too far off, when a Republican president nominates a Supreme Court Justice married to someone of the same sex, maybe even with the sanction of 'orthodox' theology - with that gay Supreme Court justice casting the deciding vote that finally overturns 'Roe vs. Wade.' It could happen.
Prediction is structurally inseparable from the business of punditry: It creates the essential image of indefatigable authority that is punditry's very architecture; it flows from that calcified image, and it provides the substance for the story that keeps getting told about the inevitability of American progress.
