Libertarians in my (somewhat significant) experience are an even mix of:
Republicans who are embarassed by reactionary social positions, but who reliably support Republicans because they don't really care about social issues that don't immediately affect them.
People who would be libs if they grew up in a blue state, but they grew up in a red state so they would be embarrassed to be Democrats (and by virtue of being on the outside share many leftist critiques of Democrats).
Hardcore reactionaries who only want to put a better gloss on "tear down the state so I can hurt and exploit whoever I want."
Cranks.
Group 2 can be brought around with a little effort, and maybe a sliver of Group 1 with a lot more effort, but there's a lot of people who are basically lost causes.
