If this is a no-win situation for Comey, he brought it all down upon himself by NOT recommending prosecution of Hillary back in July.  Subsequently, by all accounts he faced an internal rebellion by a significant number (if not majority) of FBI agents who were aghast at the travesty of justice that was his exoneration of Hillary.  He is now merely trying to play damage control after likely having faced the imminent threat of others in the FBI coming forward publicly, in an unprecedented manner, with more damning information on Hillary despite the normal chain of command.  However, I think that it is too late for Comey to save his butt, whatever the outcome of this election.
