We’ll see whether Comey’s decision is good for Hilary, yet I assert, it’s better for Trump.
Consider; Comey’s decision hardly praised Fatso. Rather he was disdainful approaching contempt. Were she indited, the D’s, hardly a stupid party, would have gotten rid of her. That would have opened the door wide for Biden, a far more likeable persona and better candidate that Trump would have great difficulty defeating. Count your blessings.
As for why this happened, it's all about the Clinton (sleeze and graft) Foundation. The pitch to O and the AG is there plenty of money in there for everybody, if we just get along.
