Eh, why not? Here’s the thing. President Obama has shown a remarkable tendency to operate outside the usual cabinet structure. He prefers to do most business via his insider circle of appointees, preferably those not subject to Senate confirmation. The Secretaries end up just implementing whatever policy they are handed.
And of the possible nominees for SecState, Kerry at least has the advantage of being highly likely to get through the confirmation process with little fuss. The comity of the Senate means no one is going to press him too hard on his qualifications, which, from here appear to be tissue thin. His record consists of being wrong on just about every important issue, which fits in well with the rest of the current administration.
We might also hear who will be replacing Petraeus at CIA. No idea who they’ll chose for that.
And rumors are still swirling over who will take Leon Pannetta’s place at DoD.
