Well, it depends what you mean by a libertarian. Arguably Bill Clinton moved his party in a libertarian direction in the following ways: He largely reconciled it to the free market. He strengthened its adherence to the pro-choice positions on matters of morality and culture. He embraced the libertarian or "designer" position on the goodness of the unlimited progress of technology and biotechnology. He kept his party on the side of activist Court that would strike down state laws on the basis of an evolving conception of the "liberty" protected by the 14th Amendment. Of course, of course Clinton is no perfect libertarian, and I would add that an excessively liberationist Court or conception of designer biotechnology would surely end up bringing us unprecedented "statism" or tyranny. Still, if I were a libertarian, I might conclude that President Bush is further from my key principles than President Clinton.
