While I'm not sold on Rand yet (every two steps forward, there seems to be a step back with him), a Rand/Ron ticket is something I wouldn't hesitate to get behind. Or if Ron was attached as Secretary of State or Treasury.
Although Judge Nap might be a better choice for the Liberty Movement. Smart, eloquent, likeable, credible, and for better or worse, he doesn't have the Paul aura/stigma attached to him. The MSM isn't above using the Paul surname as a weapon to your average voter.
