You have one: Ron Paul. But because he's not a hawk who jumps at any opportunity to spend soldier's lives and taxpayer money to defend other nations' borders, he's vilified and ignored by the RINOs. And any Republican who can't see that Ron Paul is the only true conservative running may very well fall into that category.
I believe that Ron Paul is the only candidate who entered politics becauase he loves his country and wants to keep the USA from falling into the abyss. He is a real patriot.
