Its not exactly 100% libertarian, but he outlines a plan to end both wars, cut entitlement spending, change the role of the Fed (they cant set short term interest rates anymore), and run a budget surplus. He talks a lot about the dangers of inflation and a weakening dollar.

Some of his solutions are admittedly a little liberal; he wants to only give social security and medicare benefits to poor people, he wants to liberalize immigration policy so we have a bunch of young new workers to tax to prop up said entitlement programs.

He wants to eliminate the death tax, dividend taxes, and corporate taxes, but he actually wants to make income taxes more progressive because he feels that when you account for payroll taxes the current tax system isnt progressive enough.

The book reads kind of like a mix of Dennis Kucinich and Ron Paul. Very anti-war, critical of the Fed (said they caused the crisis by creating bubbles), wants to balance the budget and curb inflation, but some of his solutions involve keep tax rates steady for rich people, and reducing their entitlement benefits ("means testing). Overall, it may sound anathema to some of you, but for me, it hits all the high points that I care about (get out of Iraq, take power away from the Fed, end the american empire and balance the budget) while using a more "moderate" approach that the average person might buy into.
