The article notes but does not explore the real problem facing the American right which that the Reagan coalition was an unholy one, destined always to fall asunder.

Fiscal "conservatives" are keen on limited/small government - since money is power, high taxation provides government with the conviction that it knows best how to use that power, and disenfranchises the individual. A belief that governments should spend as little as possible to maintain society, and leave the rest up to the market and the individual is a highly libertarian stance.

Social conservatives however, think the government should be regulating people's morality and personal choices. They believe that their (invariably religious) moral framework should be applied to everyone, by statute if necessary. They love the government and its interference. The legislation they try to propose would make the old Politburo blush.

Social conservatives are, by inclination, adherents of the state knowing best. Properly, they belong in the far left. The right should believe in personal liberty first and always, not just when it comes to the chequebook.

(It should be noted that a similar fault-line exists across the floor, where some left wingers believe in both personal civil rights and the government's right to tax one bloodless for the benefit of the feckless).
