Thats what Libertarians would like you to believe. :)
Many libertarian principles are enshrined in our Constitution. But, these libertarian principles did not engender nor do they encompass our Constitution.
Libertarians oppose our republican governmentit is far too restrictive for rugged individualists. As a Paleo, you must believe in States rightsthis is anathema to Libertarians.
Ultimately, Libertarianism is a philosophy, not a form of government. Start talking about the realities of politics and its adherents eyes glaze over. Suggest compromise and watch them go ballistic. Its almost a religious thing.
I have encountered this. Some of these folks would pass up a compromise just because it doesn't go all the way. I have tried to explain that some things take time, that Rome wasn't built in a day, to little avail.
