Libertarians are the left who support conservative economics, so their role when they show up among conservatives, is to turn them into liberals, while keeping their economic conservatism.
The problem is that libertarianism breeds liberal voters, not conservative voters.
“The problem is that libertarianism breeds liberal voters, not conservative voters.”
Can you support that statement?
Also, there’s not really anything called “conservative economics”. Classical Liberalism, sure. Libertarian Economics, sure. Austrian or Chicago School Economics, sure. Your supposed hero was an admitted acolyte of “fusionism”, which relies on what he called “libertarianism”. “Conservative economics” is a misnomer.
