If McCabe is just simply corrupt he will roll and testify about criminals both above and below him. He knows all the dirt on all of them. To keep out of jail he may do this. If he is a true committed ideologue he just might fall on his sword. He is going down, either softly or very hard. It is his choice.
If I were Hillary, Loretta Lynch, Comey, Rosenstein and others I would be very nervous. I would not insure his life. These are big boys that play for keeps.
ps Stotze and Page have dropped off the public media. They are saying nothing to anybody in public. Have they rolled over?
I would guess that Page and Strzok crumbled immediately, and have been ratting out their bosses like true stool pidgeons. They are probably both in the witness protection program by now, safe - until their car explodes when Hillary or Obama find out from their inside cronies where they are.
