Ayers turned him down, yeah right.
I know Pompeo has alot going on at State but he's only person I'd choose for CofS. Flynn would be my first choice if he didn't have outstanding circumstances(His Turkey actions still seem idiotic, hopefully there is classified information that can excuse his apparent stupidity). ECW would be my second choice. Dark horse candidate would be Tony Shaffer, he's rough around the edges though, not sure it'd work. Pompeo, ECW, or Shaffer imho.
