That was my first thought. Protect herself, first (I was just following orders, by the book), and the Obama. Which suggests that Comey was orchestrating this travesty. I really suspect that the ‘plan’ originated with Eric Holder, after getting his marching orders from Obama and Hillary...
You think small. Holder was just a not that bright weapon. In his Presidential capacity, Obama authorized, ordered, and knowingly looked away from the whole enchilada. And even he was following orders.
This is bigger than we know.
