I think it's in bad taste to ask questions that are blatantly slanted towards Ron. Things like "Ron Paul is so awesome, why aren't the rest of you awesome?" Keep the questions about Ron Paul's talking points but don't mention him specifically. Like asking about monetary policy, debt, foreign wars. Also bringing up how other candidates have voted is good too. I liked this one: "To Rick Perry: Several months ago why did you turn down the golden opportunity to ban TSA molestations in your home state despite 99% consent by the TX legislature? And do you believe we have to surrender our liberty in order to be safe?"
So in short, let Ron Paul speak for himself.
