I may be wrong, but I don’t think it is going to be that simple. Joe and Jill like the the high life. If they are pushed out they will take Obama with them. Jill will see to it. She has been part of the grift and knows where all the bodies are buried (so to speak).
I think you are spot on about Dr. Jill. She loves this stuff. Any wife (or husband) that sticks with their mate throughout all what it takes to succeed in national politics is as committed to the goal as the candidate. See Bill/Hillary Clinton for the classic power couple.
