No one on the TOTUS-reader's staff or administration is "good." They don't make decisions, they just hold up mirrors and take orders from ayers and soros.
This is true for his staff, his cabinet (has there ever been a weaker SoS than clinton?), his appointees and his czars.
His ego is writing checks his butt can't cash.
If she were working for a real president, I think she'd probably be a very strong SOS (probably to our detriment).
As it is, however, Obama and his inner circle have taken it upon themselves to act as the de facto SOS, and as a result Clinton is essentially a figurehead.
Just another example of Obama's ego at work.
