I feel the same way to an extent. I don't agree with all of what Ron Paul says. But one thing I do appreciate is his emphasis on the Constitution and the rule of law. Whether you agree with him or not, whether you're right or left, or whether he's right or left, at least you know he'll ply by the rules and either succeed or fail by the rules, but will never break the law to get what he wants. So in fact my attraction to him has less to do with his ideology than it has to do with his respect for the law. He himself has clarified that as per the US Constitution, the Afghanistan War is illegal:

The Afghan War is legal as per international law and as per Canadian law, but US involvement is illegal as per the current US Constitution since it had not gone through the proper process.
