Anderson Cooper, one of the most aggressive moderators we’ve seen, managed to pull the population of Denmark out of his pocket during Tuesday night’s Democrat debate when he felt the need to school the candidates, particularly Bernie Sanders, on their economic policies.

That was pretty impressive. Less impressive was that someone with Cooper’s insistence on facts let so many slide when the topic turned to guns. Sanders was the first to bring up the infamous “gun show loophole,” which Cooper let slide.
