Nobody Obama nominates would be good, so just take this card away from him and stall on the nomination process until after the election.
I come at this from a slightly different angle. I believe that if Kathryn Ruemmler is chosen, it will in part be because Obama wants her to keep quiet. Therefore he will reward her for her prior covering up for Obama, and he will buy her future silence as to Obama’s assorted malfeasances.
Obama and his thug regime have done this multiple times before. He rewards those that lie for him, or remain silent for him, or otherwise cover up for his illegalities or other dastardly deeds. They will get promotions, or monetary rewards, or other benefits for having kept silent. Obama and his regime are crooks of the first order.
