Imagine what it would be like if one of the Founding Fathers magically came back in our time. That's what Ron Paul is like. He stands for what the Founding Fathers stood for. He's one of the only candidates from either main party that will not take money from special interest groups. It's refreshing and gives me hope. None of the other candidates (Romney, Giuliani, etc.) are as knowledgeable about the Constitution as Ron Paul is. In one of the debates Romney said he'd consult with his lawyers in order to figure out if he could declare war. Ron Paul (who very rarely makes any kind of attack on another candidate) exasperatedly pointed out that only Congress can declare war and if Romney were familiar with the Constitution Romney would know that. None of them are as passionate about protecting our personal sovereignty and freedom as Ron Paul is. If you love liberty, you will find hope in Ron Paul's message.
I think the best way to understand who Ron Paul is and what he stands for is to watch some of the many videos online or to look through his website.

Nov. 9, 2007 - primary elections
Anyway, now that you've posted these videos, I've been listening to some of them, and I'm really intrigued. I wish I could truly know the heart and mind of the candidates to know what their true motives are and what they really think. Anyway (again), in order to vote for a presidential primary, would I have to declare myself Republican? That sounds a little repugnant to me (I don't want to align with *any* party), but I might do it to vote for him.
