Moderators are not supposed to preside at a hanging - although they are supposed to ask tough questions.
the FNC moderators are partisans, clearly - and should be shunned because of it.
Actually, they are supposed to stick the knife in and twist, the idea being to bring out any candidate weaknesses, before they manifest themselves after the candidate wins office. I don't have a problem with Cruz being targeted. If he's any good, he'll survive the baptism of fire. And I won't whine that he was unfairly treated if he crashes out. Life is unfair. It's the nature of the game - there's only one winner in this primary cycle. The rest get, at best, consolation prizes.
