That's the problem. The only debates that the panel of neo con "top tier" candidates will agree to appear in are those sponsored by the establishment-owned media (i.e., all the MSM debates).
If a Liberty org like Campaign for Liberty, or a "non partisan" liberty org were to host it, only RP and Gary Johnson would show up. Because that debate would be fair, balanced and focus on the top 2-3 issues, and actually allow a real "debate" (hello!), none of the other candidates would dare show their faces, because their true colors would be exposed very clearly.
That's what these sham debates are doing too, they aim to "expose" RP as a fringe candidate, or ignore him.
Problem for them is that most Americans believe in Liberty if they will take a few minutes to think about it. That's why this movement is growing so rapidly.
Reminds me of a George Washington quote: "Liberty, when it begins to take root, is a plant of rapid growth."
"It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a rEVOLution before tomorrow morning." - Henry Ford
