The dream of setting up a utopia far from the craziness of current events is as old and pervasive as human civilization. This is simply a Libertarian version of the search for the Promised Land.
The article omits to mention, of course, the pre-eminent reason why NH and the runner-up states were chosen; they all have relatively small populations which is a prerequisite for any Libertarian invasion. 20,000 Libertarians aren't going to do diddly squat in a state the size of NY or California, but in a small state they just may have an impact, although not necessarily for the better.
I nominate NH for some sort of bravery and public service award. By acting as a Libertarian "sink" they are taking the loonies out of our hair and concentrating them all in one place. That lets the rest of us enjoy a little more sanity. Once they get 20,000 in there, they should erect a fence around the place so they can't get out again.
