There have been a lot of thoughtful answers to this question. I would just like to add this.
Ron Paul is a wise man. And anyone who hears him speak knows he is very knowledgeable about economics, history and foreign policy. Not only that, but if he is elected, he will surround himself with people who are knowledgeable. And on areas that he is not as knowledgeable, he is open to gaining more knowledge.
Right now, I am reading "Imperial Hubris: Why The West Is Losing the War on Terror" by Michael Scheuer, the former head of the Bin Laden unit in the CIA (who retired in 2004). It is packed with information. Even if someone read up to page 20, he could learn a lot.
This book is one of the ones Ron Paul recommended to Giuliani. After having read only part of it (so far), I believe it's a book that should be read by anyone who aspires to become president. But since Giuliani is unlikely to benefit from his assigned books, I think they are there for *us*.
Remember, in the days of the founding fathers, how educated the average person was? The Federalist Papers were written to be understandable to the average citizen (living then).
Also, on June 15, Ron Paul had a rally in Kansas City. In the question and answer time, someone asked what we could do for him, besides donating our money/time. He said the best thing we could do is to educate ourselves, so that when questions came up, we would be able to answer them convincingly.
