The appointment of Bill Richardson, as Commerce Secretary, must have been a bit of satisfying retribution for the Clintons as they knew how much Richardson wanted to be Secretary of State. Maybe that was even a part of Hillary's thinking as she pondered whether or not to accept the appointment. As we know, they, and all 'good' politicians, never forget and the Clintons considered Richardson's endorsement of Obama the ultimate betrayal.
These two Secretaries are the real rivals, not simply "competitors", as Richardson said in his press conference address. Let's see if this spirit of koombya infects all of Obama's so-called Cabinet of Rivals. This should keep things interesting.
