WHY DO Republicans call Libertarians Liberal When they are...?

the Liberal ones!? Republicans Spend a lot of money, they start pointless Wars, get involved in Foreign Affairs(both Wars and Foreign Affairs were things the liberal and progressive democrats did before Nixon and later the Bush's). Republicans use the Federal Reserve to print all of the money they want to spend, spend and spend. Yet when Libertarians like Ron Paul, Alex Jones, Michael Badnarik, try to end these things they get called Liberal! Same when Libertarian groups bring up ideas from Milton Friedman, and Murray Rothbard those guys get called liberal! Even most of the conservative Forums most of the people diss Libertarians and call them Liberal! Why is this, Republicans like Bush, Palin, Romney, Huckabee, and many others are Liberal.
