“This suggests that libertarian conservatism will overtake progressive liberalism as the political philosophy of choice.”
More than likely. Not entirely a good thing in my view, but I think it’s where things are headed in the long term.
(And before I get myself into an unwanted debate with the various FR libertarians, let’s just say that I find the more libertine aspects of the philosophy to be problematic.)
Libertarian does not equal libertine.
