If this spares us from hearing ignorant questions like, "How has the national debt personally affected each of your lives?", then I'm entirely in favor of more active moderation.
I agree. In addition if (for example) a candidate gets asked "What is your favorite flavor ice cream?" and the candidate response "Sprinkles are really great. Some people call them jimmies, which is cool and all, and I respect the people that do --but they're pretty good. My opponent here will tell you that peanut butter topping is the best, but what you need to know is that peanut butter topping will increase the deficit and destroy America."
...and then the moderator should go "Candidate X, you spoke about your favorite topping --but what is your favorite ice cream?"
