What are Bob Barr's positions?

And why is Bob Barr even thinking about running for President with only 6 months to go? Bob Barr answers on Reason.tv

The driving issue this year is due process, our only hope for putting a brake on the accelerating breakdown of our American civil and natural liberties, an emergency brake perhaps.

Due process not only applies to the microcosms of a business being wiretapped, a person being rendered, a home being disrespected, but it also applies to the larger events. It is Congress's job to hold a trial of sorts before the dog of war is unleashed, before the President is sicced on any land. They failed in restraining President Clinton, and they continue to fail with President Bush. Instead they try to vest the power elsewhere childishly, namely with the executive himself, contrary to the Constitution, per Federalist 69.

The President is to be commander-in-chief of the army and navy of the United States. In this respect his authority would be nominally the same with that of the king of Great Britain, but in substance much inferior to it. It would amount to nothing more than the supreme command and direction of the military and naval forces, as first General and admiral of the Confederacy; while that of the British king extends to the declaring of war and to the raising and regulating of fleets and armies -- all which, by the Constitution under consideration, would appertain to the legislature

Both parties have failed to stop government anarchy. Barr speaks of the rule of law, applied to government.
