With more and more people feeling disillusioned with what has been happening in Washington, its no surprise they're looking for an alternative. The Ludwig von Mises Institute promotes free-market thinking at its purest, and can be categorized as the Austrian School of Economics, or simply Libertarian Economics.
Anyways, I found this interesting piece showing that the Mises Institutes's website traffic is up 80% year over year. Clearly more people are looking into this line of thinking.
Its a great site by the way and they provide their viewpoint as well as alternatives about many current issues. Ron Paul is one of their more popular supporters.
