You live by the sword, you die by the sword.
Hillary only got as far along as she did because Comey and McCabe covered for her and did a sham investigation. So she is indebted to them to have gotten far enough along to even be the nominee.
But Comey got caught in a bind and his own corrupt organization inadvertently cornered him. He had promised the House Committee that he would report any new findings on Hillary even though he was letting her off. Then he found out that McCabe had been sitting on those emails that huma and the weiner had and had not even looked at them. McCabe had them for a month and still had not looked at them, but they had been sent to McCabe by the Southern District office that was doing the investigation of the pervert. So now Comey was in a bind. He had promised one thing to the Committee but his deputy mccabe had been hiding shit.
Sorry if the swamp house-of-cards plan collapsed and their various little schemes got all tangled up.
I will let the IG say more on that.
