What's the difference between a conservative & libertarian?

It's probably true, though some libertarians feel uneasy admitting it, that among libertarians, there are a bit more former conservatives than former liberals. It's probably easier for a Repub to warm up to cultural liberalism than it is for a Dem to accept free-market economics. Plus, the GOP probably is a bit more egregious at violating their claim of being pro-free market than the Dems are at violating their claim of being pro-civil liberties. So, among those libertarians who were formerly of a different political persuasion, a majority probably come from the conservative side.

Because of libertarians' support for free-market economics, liberals often have a hard time distinguishing between the two. This damning piece should highlight some of the differences.
