It was first rumored that Comey flipped, a few days ago. No way in hell he was in it from the beginning. He's still Fake and Gay, literally. It just means he struck a deal to save his own ass. He was also in charge when Hillary was being investigated so it's safe to say he has the real info on her investigation and was holding onto it as leverage in case the shit hit the fan. Otherwise he would have just taken care of her then after the election if he was ourguy. He's not. But if he can help deliver the kill blow to Hillary, I can live with this choice.
