Let's see:
George Washington (a signer of the Constitution and President of the Constitutional Convention), without any Congressional approval, commanded armed American troops to put down the Whiskey Rebellion against American citizens on American soil. It should come as no surprise that the leaders of Whiskey Rebellion didn't seem to think that Congress had the authority to levy taxes.
Thomas Jefferson (principle author of the Declaration of Independence), with the full support of his political allies and enemies and without any Congressional declaration of war, sent troops to Northern Africa for the First Barbary War.
James Madison (principle author of the Constitution and the Bill of Rights), again without any Congressional declaration of war, again sent troops to Northern Africa for the Second Barbary War.
Somehow I fail to see where any of the Founding Fathers seemed to agree with RINO PaulPot and his pathetic mob of followers.
All of his principles of Constitutional interpretation are cribbed from the ideology of the Anti-Federalists, the Nullificationists, the Spoonerites and the Secessionists - all historically enemies of the US Constitution - as opposed to the Federalists and the Republicans, who have historically been the champions of the Constitution.
Ron Paul uses the rhetoric of these anti-Constitution groups while simultaneously claiming to be a defender of the Constitution.
For example - the bizarre, muddled notion of "states' rights" - states have no rights under the Constitution. Governments don't have rights. They have powers.
