Comment: The moderators do not have the time or the all-purpose knowledge to be fact checking on the fly.  Candy Crowley did that last time with Romney, contradicting him and agreeing with Obama, but she was wrong and Romney was correct.  The moderators should ask their questions as well as they can - and allow the candidates to fact check each other as they wish - and leave the media fact checkers to pass out the Pinocchios later. 

The liberals who think Lauer should not have asked Hillary about her emails are simply not wanting to see their candidate held accountable.  She is a corrupt politician, but she is their corrupt politician.
